The Superior Sleeper Cache is a Cosmic Signature that can be found in known space using core scanner probes. The Superior Sleeper Cache is the most difficult of the Sleeper Cache sites, and is a rather challenging site to complete throughly. Pilots will be risking their ship when trying this or any other Sleeper Cache - but an experienced pilot will find the site worthwhile to complete.

All Sleeper Caches require both Data and Relic Analyzers. All ships except Capital ships can enter the site. The minimum probe strength to scan down the site is 104.

Those adventurers who are unfamiliar with the basic concept and principles of these sites should read through this basic Preamble to get up to speed first.

Quick Guide

Entry

1. Scan down the site.
2. Hack the entry container. Enter the site.
3. If you land in the Turret Room, take the nearby Spatial Rift to enter the Solray Power Plant. If you're already in the Solray room, proceed to #4.
4. If you land on the farther side of the site near the Remote Reroute Unit, activate the nearby Rift. You may incur some damage as you warp through the Solray Unaligned Power Terminal.

Always run the Solray Room first.
Solray Power Plant

5. Hack the Solray Observational Unit.
6. Open container, and observe the "disc" it grants you. It can either be Infrared, Gamma or X-ray. 7. There are three containers in this room. Place the "disc" into the container which matches the name of the disc. This will align the Solray Power Terminal, which considerably reduces the damage it deals.
8. Approach the container in between the two rifts near the Solray Observational Unit. Drop your Mobile Depot there. Hack the Storage Depot and loot it.
9. Refit to your capacitor stable local repairer fit.
10. Approach the Solray Power Terminal and hack all containers. You may cargo scan them first while the Mobile Depot is up if you wish to skip unworthy containers.
11. Refit back to your generic fit, making sure to bring a Microwarpdrive. Drop all loot and unneeded modules in the Mobile Depot and bookmark it.
12. If you're in a frigate or cruiser that has less than 70,000 EHP of omni-resists, consider skipping Phase 3 and proceed to Phase 4, as failure in that stage will cause you to lose your ship. Take the Spatial Rift near the Gamma Ray container into the Turret Room.

To attempt the Mine Room, take the rift near the Solray Observational Unit.
Mine Room

13. Hack the Remote Reroute Unit.
14. Take the Rift nearby to head back to the Rift near the Solray Observational Unit. Take the rift near that object (the Infrared Alignment Unit container is nearby). You may incur some damage upon entering, but is should be manageable.
15. Move around a bit in the same direction slowly (no MWD) until a Remote Defense Grid Unit spawns. Hack it.
16. If successful, hack the nearby Storage Depots.
17. Align back to the Solray Room - visible in the distance - and burn the Microwarpdrive or Micro Jump Drive; alternatively, warp out and back in immediately. Continue on to Phase 4.

Sentries on Duty

18. Upon entering, look for the nearby Remote Defense Grid Unit. Select "Keep at Range" (5000m) on it. Start hacking it.

WARNING: Failure could mean the loss of your vessel. In the event of failure, warp out and do not re-enter without a strong active tank or solid remote repairs with a strong local buffer.

19. Upon successful hack, immediately burn with the Microwarpdrive to the right towards the Sentry Repair Station. You have enough time for about 2 hack attempts. Hack it. Wait for all Sentry Towers to be eradicated.
20. Hack all loot containers at your leisure. Do not approach the Plasma Chambers nearby. Use "Keep at Range" (2500m) for the can closest to those chambers and approach slowly with no propulsion module active.

WARNING: Do not aggress the Plasma Chambers except under specific circumstances (detailed below). They have enough power to wipe a battleship clean off the field.

21. If you are in a frigate or any cruiser/battleship that cannot handle extreme damage per second (DPS), this will be the extent of possible completion. Go back to your Mobile Depot, refit to travel fit, collect all loot, pick up the Mobile Depot, and warp out.

Otherwise, continue to Phase 5.
Archive Room
You will need a Strategic Cruiser or Nestor to handle this room, with at least 2000 EHP/sec active reps and minimum 50K EHP of buffer. You must be able to both repair and tank considerable damage. A super-tanked cruiser or battlecruiser (such as a Maller or Prophecy) may be capable of surviving for a time with proper use of the Vessel Rejuvenation Batteries. To ensure that loot is not lost in the event of failure, eject loot at regular intervals to be returned to later.

22. Before running the Archive Room, store all loot and unneeded modules in a Small Secure Container or nearby station. Make sure to bookmark the can; containers cannot be scanned down with combat probes. A safe spot works nicely. Bring the mobile depot.
23. Starting from the Turret Room, hack the Hyperfluct Generator. If successful, take the rift and skip to 27.
24. If unsuccessful, then "Keep at Range" (5000m) from the Vessel Rejuvenation Battery. Lock up one of the Plasma Chambers. 25. Hack the Vessel Rejuvenation Battery. Wait two seconds after the hack is completed and make sure you are within its protection cloud. Immediately thereafter: 26. Aggress one of the Plasma Chambers. Immediately proceed back to the revived Hyperfluct Generator. You will have sixty seconds before the alarm is sounded, which will spawn 16 new Sentry Towers. Hack it quickly. Take the rift.
27. There are a number of damage clouds in this area. Approach the Archive Cerebrum Chambers; a propulsion module will help.
28. Hack the Remote Targeting Defense Augmentation Unit. A Pristine Storage Depot may spawn nearby. Hack it and loot it.
29. Start hacking the Cerebrum Maintenance Chambers. You will need three (3) Intravenous Oscillation Fluid objects. Failure of these hacks may spawn additional Sentry Towers. You may elect to destroy them. Light drones are recommended due to their 50m signature radius.
30. Double-check that your ship is fit properly and prepared.
31. Approach the Central Archive Cerebrum. Place only the 3 Intravenous Oscillation Fluid objects inside it.
32. At this point, start watching the messages in Local more intently. Storage Depots will begin to spawn nearby. Damage from Shockwaves will also commence after a short time, and increase in magnitude. There may be one Depot which is distanced afar from the regular group. You may cargo scan containers to evaluate their worth. When finished (or dead!), warp out of the site, wait for it to despawn. Warp back to any bookmarked containers left inside the site, and continue on.

Ship Fittings

Frigates not capable of running a Superior Sleeper Cache in its entirety.

In particular, frigates are not suitable for:

  • Checking if the Alarm has been activated in the Sentries on Duty room (instant death)
  • Running the Archive Room (unable to tank excess of 1500 DPS)
  • Running the Mine Room safely. Completion is possible, but should you fail, you will lose your ship

Otherwise, a Heron or Magnate can complete all other sections of the site.

Icon warning.png Exercise caution when altering these fits. These fits have been demonstrated to work, and alteration may result in failing the site in an efficient fashion or losing the ship.

  • As long as you have Capacitor Systems Operation and Capacitor Management to II, you may simply swap the capacitor recharger for a Small Compact Pb-Acid Cap Battery, but the Afterburner will have to be used only when needed.
  • As long as the fit can sustain about 40 EHP/sec (EFT/Pyfa figures) indefinitely, it's good enough.
  • Also make sure the Analyzer(s) are set to Auto Repeat OFF.
  • Cargo scan the containers before you use this fit to identify which ones are junk and which ones are not (use a fleet of yourself to allow tagging of containers)

Use a cargo scanner if possible after completing the two data hacks in the Solray Room.

It can be helpful to use a Small Secure Container (anchor it and set a password!) more so with the Magnate than the Heron. Leave the Secure Container in the Solray Room and bookmark it, and store the loot, cloaks and probe launchers inside it. Bring the Mobile Depot into the Turret Room to refit for the Cargo Scanner after the data hacks are finished.

Walkthrough

Entry

Having scanned down the site, warp to the result.

Look for a Hyperfluct Generator can. If a Spatial Rift is already up, then someone is there, or has been there.

Icon warning.png WARNING:

If the site has already been accessed, quickly check the Directional Scanner in a 1 AU radius to check for wrecks. If there is one at the site, do not enter. (You can also check zKillboard.) The Rift in the entry room might send you straight into the Turret Room, which might have had the alarm tripped. Unless you have a strategic cruiser or battleship with strong resistances (an overtanked Maller with two EM and two Thermal Hardeners works too), you'll be alpha'd off the field by 16+ Sentry Towers. There is no opportunity to warp out, cloak up, or escape through the nearby rift -- they aggress almost immediately.

Otherwise, continue on with the hack of the Hyperfluct Generator can:

CAN DIFFICULTY: 7/10 DATA [RED HACK]
SUCCESS: The Spatial Rift is spawned, which leads into either the Sentries on Duty area or the Solray Power Plant. Capsules, Dreadnoughts, Carriers, Supercarriers, Titans, and Freighters cannot take the rift.
FAILURE: You have two minutes to attempt a successful hack of this container. If a successful hack is not completed by that time, the site despawns.

Activate the rift.

Entry after successful hack
  • If you land in the Turret Room, approach and activate the nearby Spatial Rift to warp to the Solray Power Plant.
  • If you land in the Solray room, there are three places you may land. Look carefully for three containers, and based on which one you landed near, take the appropriate action:
  1. Solray Gamma Alignment Unit: Stay here for now.
  2. Solray Infrared Alignment Unit: Approach the Solray Infrared Alignment Unit.
  3. Solray Radio Alignment Unit: Take the nearby rift which will send your vessel over to the Solray Gamma Alignment Unit zone, although it can also direct you over to near the Infrared Alignment Unit.
Note: The destination is random for each site and changes from one site to the next, but it will remain consistent within any one site.

Solray Power Plant

Icon warning.png Stay on the side opposite the Solray Power Terminal—it deals ~600 dps omni-damage without being aligned. If someone has already entered, you will need to ascertain whether the Power Terminal has been aligned. There are two ways of doing this: first, the name of the container will have changed; second, you can inspect the Alignment Unit containers to see if the correct disc was placed inside. As a last resort, bring in a cruiser that can tank or have a friendly logistics cruiser capable of restoring ~650 EHP/sec (roughly 250 raw HP/sec).

Near the Solray Gamma Alignment Unit container, there is a structure named the Solray Observational Unit. When successfully hacked, pilots can obtain an "alignment disc" which, when placed in the proper container, reduces the strength of the damage cloud created by the Solray Power Terminal. When warping through the Power Terminal's damage radius, vessels may sustain some damage but this damage is manageable.

A
Hacking the Observational Unit

Hack the Alignment Unit.

CAN DIFFICULTY: 7/10 DATA [RED HACK]
SUCCESS: The hacker is free to open the container and collect the alignment disc.
FAILURE: No penalty.

Zoom out to locate the correct container to place the alignment disc. There are three: Infrared, Radio and Gamma Ray Alignment Discs. The Infrared Alignment Disc goes in the Solray Infrared Alignment Unit, the Gamma Ray Alignment Disc goes in the Solray Gamma Alignment Unit, and the Radio Alignment Disc goes in the Solray Radio Alignment Unit. Collect the discs and burn over to the appropriate container. To load the Radio Alignment Disc, take the rift near the Solray Observational Unit to warp over to that container, then take that rift back over to the main area.

Upon stabilizing the Solray Power Terminal
Using the crystal disc, the alignment is now correct and the Solray Power Terminal is stable.

With the Solray Power Terminal aligned, it will deal considerably less damage while a vessel is within its damage radius (~14-17km).

Drop a mobile depot near the lone (Dented or Mangled) Storage Depot which is between the Solray Gamma Alignment Unit and the Infrared Alignment Unit. If your Relic Analyzer is equipped, hack the depot while the mobile depot is setting up. Otherwise, wait near it (do not cloak, otherwise the site may despawn) and after it is ready, refit into the capacitor stable self-repper fit with a Relic Analyzer. It may be prudent to cargo scan all nearby containers including the ones inside the Power Terminal's proximity to check for dead-end worthless containers (as it is possible that some may be empty).

CAN DIFFICULTY: VARIES (RELIC) [YELLOW TO RED HACKS]
SUCCESS: Contents are ready to be looted.
FAILURE: No penalty.

With 50% resistances to all damage types, the damage cloud deals ~15 damage per second. A ship able to repair more than 30 Effective Hit Points (EHP) per second indefinitely is completely sustainable.

Afterwards, refit back to the generic site running fit with a Microwarpdrive and both Analyzers.

For the frigate pilots, consider skipping the next room and moving on to Sentries on Duty, below. A Strategic Cruiser or Nestor is best for attempting the Mine Room. An overtanked Stratios (2 plates and 2 large shield extenders) should also be fairly safe. Frigate pilots will lose their ship upon failure.

Mine Room

The recommended tank for this room is 70,000 EHP. It can be done with less, so long as the pilot does not fail any hacks. If you wish to attempt this section with a frigate, use the cheapest T1 exploration hull (the virus strength is a requirement) equipped with a Medium Azeotropic Restrained Shield Extender, a Damage Control I, a Limited Adaptive Invulnerability Field I, and a Data Analyzer, with nothing else. In that case, do this room after completing the Turret Room.

To access this room, take the rift near the Solray Observational Unit. The Solray Power Terminal must be aligned first for the rift to work properly, even if the Reroute Unit has been hacked. The landing point is next to the Solray Radio Alignment Unit. Hack the Remote Reroute Unit:

CAN DIFFICULTY: 7/10 [RED HACK]
SUCCESS: The Rift is recalibrated to point towards the Mine Room.
FAILURE: No penalty.

A successful hack changes the direction of the Rift near the Solray Observational Unit to point towards the Mine Room instead of near the Radio Alignment Unit. Take the nearby Rift to head back to the main area, then take the rift near the Observational Unit into the Mine Room itself.

Expect to sustain ~800 damage upon landing or shortly thereafter from a hidden mine. Upon landing, you should see a Remote Defense Grid Unit. Do not activate a Microwarpdrive if you have one equipped. The Remote Defense Grid Unit is approximately 7km off the beacon; some slow manual piloting may be required:

CAN DIFFICULTY: 10/10 [RED HACK]
SUCCESS: A Pristine Storage Depot and possibly one or two lower grade containers are spawned.
FAILURE: Ship will sustain between 10000-25000 damage.

If successful, continue by hacking the spawned containers:

CAN DIFFICULTY: VARIES (RELIC) [YELLOW TO RED HACKS]
SUCCESS: Contents are available to be looted.
FAILURE: No penalty.

When finished, you may Micro Jump Drive back to the main area, burn a Microwarpdrive, or just warp out and warp back in. Continue on to the Turret Room.

Sentries on Duty

Turret Room Visual Guide

Icon warning.png WARNING:

1. If the Alarm has been tripped in this room, there can be in excess of 16 Sentry Towers active, and frigates will not stand a chance. There also can be no warning that the Alarm has been tripped. Overtanked Mallers and other hardened ships can survive the initial damage and subsequent DPS. If coming from the Solray room, the message indicating that the Alarm has been tripped shows up only after the ship is already in warp.
2. Do not apply any hostile module or weapon onto the Plasma Chamber structures except in very specific circumstances (detailed below). They have enough power to alpha a battleship off the grid (or a small fleet).
3. Do not engage the initial Sentry Towers. Doing so will instantly trip the alarm and spawn the 16 Perimeter Defense sentry towers. The maximum number of Sentry Towers that may be active appears to be 32 (16 Perimeter, 6 initially deployed, and 10 'proximity' ones).

This room can be challenging, but for frigate pilots, this is generally the most lucrative portion of the site.

The following images are included to provide context and further guidance:

Turret Room Walkthrough

Entry message
The area you're entering has several sentry guns active, and there are indications that many more may be hidden in an inactive state. The sentry guns surround a lucrative cache of storage depots and another Hyperfluct Generator, possibly opening a way deeper into the complex.
Hacking the repair station early does nothing

Start from the Solray room, leaving the Mobile Depot near the lone Storage Depot.

Make sure to do three things before attempting this room:

  1. Bookmark the location of the Mobile Depot in the Solray Power Plant.
  2. Drop all loot and unneeded modules into the Mobile Depot.
  3. Refit into the appropriate fit.

Take the Spatial Rift near the Solray Gamma Alignment Unit container. The Sentry Towers will not aggress unless a ship strays too close to the loot containers.

The Remote Defense Grid Unit in the room has three functions: first, it disables any proximity-based Sentry Towers from activating. Second, it re-wires a hostile Sentry Tower into a friendly one. Third, it recalibrates the Vessel Rejuvenation Battery into one that can be hacked to configure it to repair the friendly Sentry Tower. If a ship approaches the Storage Depots and ignores the Remote Grid Defense Unit procedure, then not only will the 6 initial Towers aggress, but up to 10 additional new Sentry Towers can spawn.

First, hack the Remote Defense Grid Unit. Take your time on this hack, there is no rush. The newly-converted Tower will then aggress the other 5 Sentry Towers, and in turn take damage itself. It can't sustain the incoming damage for long.

Icon warning.png WARNING: A present bug in the site seems to indicate that failure of this next hack will spawn the Sentry Towers regardless of whether a successful rehack has been completed. So the countdown to the perimeter Sentries will not be actually canceled, no warning in Local that they are about to spawn, instead you will find 16 Sentry Towers will spawn anyways. In a frigate, warp off the site immediately if you fail the hack. Cruisers and above which can run the Archive Room may choose Plan B.
CAN DIFFICULTY: 9/10 DATA [RED HACK]
SUCCESS: The closest Sentry Tower becomes friendly, and aggresses the other Sentry Towers to blow them up, and will in turn begin taking damage itself from the other Sentry Towers.
FAILURE: A timer is generated which will activate the Alarm in 45 seconds. When the 45 second timer is up, the RDGU explodes and there is no other way to proceed without strong tanking abilities. At the 45 second timer mark, the site spawns the 16 Perimeter Defense sentry towers, for a total of 22 Sentry Towers. Frigates will not survive.
Approximate DPS of all 16 Perimeter Towers (varies)

For Cruisers and above, there is Plan B (below).

After hacking Remote Defense Grid Unit
By hacking the remote defense unit, you've managed to rewire one of the sentry guns nearby. It now considers you friendly and the other sentry guns as hostile and will start attacking them.
Hostiles targeting friendly Sentry Gun
The hostile sentry guns in the area have started targeting the rewired sentry gun. Might it be possible to help it out in some way?

Immediately after hacking this container, active the Microwarpdrive and burn towards the Sentry Repair Station located near the right of your present position. Hacking the Sentry Repair Station will cause it to provide armor and shield reps to the friendly Tower. (The friendly Tower cannot receive remote repairs from ships.) There is enough time for 2 hacks, maybe 3 fast hacks, before the hostile Sentry Towers destroy the friendly Tower:

CAN DIFFICULTY: 8/10 DATA [RED HACK]
SUCCESS: The Station will provide shield and armor repairs to the friendly Rewired Sentry Gun.
FAILURE: No penalty, although if a successful hack is not completed before the hostile Sentry Towers destroy the friendly Tower, then some Towers will remain.

Hostile Towers do not appear to aggress ships even if the hacking the Sentry Repair Station is unsuccessful. Instead, the hostile Towers appear to keep incurring damage and are eventually destroyed, even with the Rewired Sentry Gun destroyed. This is another bug of the site itself. Should it be fixed in the future, simply revert to Plan B. Do not aggress the Sentry Towers with weaponry - it will instantly trigger the 16 Perimeter Defense Sentry Towers.

After hacking Sentry Repair Station Preservation Unit
You have successfully turned the focus of the repair facility to the rewired sentry gun. This will not only repair it from incoming damage, but also speed up the destruction rate of the hostile sentry guns now that they no longer enjoy the benefits of the repair station.

Assuming a successful hack of the Sentry Repair Station, simply sit near the Repair Station and wait for the hostile Towers to be eradicated. Do not approach the 3 Unstable Plasma Chambers located north of the warp-in. Getting too close to these could be fatal, and will also trip the alarm.

Upon approaching Unstable Plasma Chambers
These Plasma Chambers seem volatile. You should be careful around them lest they explode.

Hacking the Sentry Repair Station before the Remote Defense Grid Unit does nothing, although a message appears in Local: "Hacking the repair station has no discernible effects on anything in the vicinity. The station continues to provide repair services to to the nearby sentry guns."

When all is clear, the loot is there for the taking, and pilots may hack and loot in peace, with no particular danger:

CAN DIFFICULTY: 6 - 9/10 RELIC [YELLOW to RED HACKS]
SUCCESS: Contents can be looted.
FAILURE: No penalty.

Do not hack the Hyperfluct Generator container yet.

While working on the hacks, avoid using the Microwarpdrive, use "Keep at Range" (2500m) on the last can near the group of Plasma Chambers, and move slowly (around 100m/sec) to avoid triggering the Plasma Chambers. After all worthy containers are hacked, frigate pilots will have completed as much as they can. Take the Spatial Rift to head back to the Solray Room, refit to a travel fit if needed, scoop up any contents inside the Mobile Depot (if it is scooped to the cargohold directly, a jetcan is left behind), pack up the Mobile Depot and depart.

For the T3 Cruisers, Nestor and other similar battleship-level tanked ships, if there was no Mobile Depot left behind anywhere in any other room, you may now proceed to the Archive Room.

The Archive Room

First case: Rift Spawns immediately: otherwise, detonation required

Starting from the Sentries on Duty room, there should be a Hyperfluct Generator container. Hacking it produces two outcomes:

CAN DIFFICULTY: 9/10 DATA [RED HACK]
SUCCESS:
First case: A Spatial Rift is generated, which allows immediate access to the Archive Room.
Second case: A Spatial Rift is not generated. Here's what needs to be done:
  1. Lock up one of the Unstable Plasma Chambers. Make sure you have some kind of high slot weapon: drones will not work. Even a 125mm Autocannon on a Nestor is enough. Do not shoot it yet.
  2. Start hacking the Vessel Rejuvenation Battery, but do NOT finish the hack. When you find the core, and are 1-2 clicks away from success, get ready for the next bit below.
FAILURE: No penalty.
CAN DIFFICULTY: 8/10 DATA [RED HACK]
SUCCESS: A cloud is generated which approximates the area of healing reps. It evaporates after 10 seconds, so timing is important. The cloud will protect even a frigate from the incredible power of the explosion.
FAILURE: No penalty.

Just after you finish the hack, watch Local to see when the message pops up informing of the activation, then quickly shoot a Plasma Chamber. The Vessel Rejuvenation Battery's mad reps will protect you. Quickly turn on the Microwarpdrive over to the now-revived Hyperfluct Generator. There are just 60 seconds to attempt a successful hack before the Perimeter Defense System comes online. When that happens, 16 new Sentry Towers appear. Frigates will be destroyed. Ships that can run the Archive Room fine will be okay to repeat attempts until the Rift is generated.

Assuming the hack goes through in time, take the Rift into the Archive Room itself.

Entry message
The area you're entering was a massive archive, storing and recording millions of objects and items from around New Eden. Someone or something recently went through the archive like a tornado, leaving it almost completely ruined. It is possible though that something can still be retrieved, but it all hinges on whether the archive system can be made operational again.

Any failed hacks in this room may spawn additional Sentry Towers.

There are several obstacles in the Archive Room which cause damage: Sentry Towers, damage clouds near various objects (Smoldering Archive Ruins), and shockwaves.

Begin by approaching the Defense Targeting Augmentation Unit. From the beacon, a straight line approach is fine. Hack the Defense Targeting Augmentation.

CAN DIFFICULTY: 8/10 DATA [RED HACK]
SUCCESS: The Sentry Towers, which already have atrocious tracking ability, suffer an additional tracking penalty.
FAILURE: Standard failure result of any can in this site: May spawn additional Sentry Towers.
Upon hacking Defense Targeting Augmentation Unit
You have managed to disrupt the targeting service. This will make it much harder for sentries in the area to score a hit.

A successful hack also has the opportunity to spawn a Pristine Storage Depot nearby. You may hack it and loot it.

Proceed on to hacking the Cerebrum Maintenance Chambers. Each functions like a normal data or relic site object: it must be hacked first before it can be opened. Three Cerebrum Oscillation Fluid objects are needed to activate the Central Archive Cerebrum; other items like the Self-Regulating Machine Gears and what not are just scrap. Hack enough Cerebrum Maintenance Chambers to get the items required:

CAN DIFFICULTY: 8/10 DATA [RED HACK]
SUCCESS: The contents may be extracted.
FAILURE: Additional Sentry Towers may spawn.
Upon hacking Cerebrum Maintenance Chambers
You have succeeded in gaining access to repair parts for the Central Archive Cerebrum.

It is advisable to shoot the Sentry Towers that lie around the perimeter. As they have a 50m signature radius, Light Neutron Blasters and light drones are recommended. Depending on the ship's fit, their absence can be enough to make sure your tank lasts long enough.

Once 3 Oscillation Fluids (or more) have been obtained, approach the Central Archive Cerebrum and "Open Cargo".

Place 3 Cerebrum Oscillation Fluids into the Central Archive Cerebrum; more is unnecessary. When this is done, a couple of things are initiated: first, the Central Archive Cerebrum will eject Storage Depots of varying grades, and shockwaves will begin to occur. The first set are tankable fine in a standard Tech III Strategic Cruiser, though the double massive shockwaves will most likely be more than most fits and skills can handle. The basic idea then becomes a question of how many cans can be hacked and looted before the incoming damage is more than can be safely tolerated.

Vessel Rejuvenation Batteries will also be ejected from the Cerebrum itself (details in collapsed "Archive Room Damage" infobox, below).

Make sure to check for other containers around the area, for those looking to complete the room fully. When finished, warp out. Those who left Mobile Depots in other rooms may need to warp back to collect them and refit for a travel fit.
