There are eight Data Shards in End of Abyss. The routes below list each location by area and floor, along with the key, item, or switch needed to reach it. The Reactor shard is the longest route and, according to the walkthrough, requires the Grappling Hook.
The route directions are from 100% Guides’ walkthrough, published September 29, 2026; a later iTechGuides guide repeats the locations and identifies that walkthrough as its source.
All eight Data Shard locations
Use this checklist to track the areas and floors before following the detailed directions. The listed access requirements and routes are walkthrough instructions.
| Shard | Area and floor | Access requirement noted |

| 6 | Waterworks, B3 | Sewer Workshop Key |
| 7 | Containment Sector, F3 | Explosive Charge; Storage Room Key |
| 8 | Lower Levels, B4 | Burnable wall |
1. Lower Levels — F1
- Go to the northern hall on F1.
- Burn down the wall there to uncover the Data Shard.
2. Habitation Sector — F1
- Find the wall just left of the Containment Sector Fast Travel Shuttle and use an Explosive Charge to open it. Take the Security Guard Keycard inside.
- Use that keycard on the door at the right end of the Habitation Sector corridor.
- Go downstairs and through the door on the left to collect the Security Chief Keycard.
- Return to the main hall and use the Security Chief Keycard on the door on the left.
- Go through the northern door to reach the shard.
3. Ventilation Tunnels — F3
- Enter the Tunnels from the easternmost Factory East entrance. Use an Explosive Charge on the weak wall to the right.
- Continue to F2, cross the upper catwalk, and pull down the ladder to F3.
- Go right and upstairs. After the ambush, take the Ventilation Maintenance Key.
- Use the key on the northern F3 door to get to the shard.
4. Factory West — F4
- In the Outer Sector, use an Explosive Charge to open the floor just outside the Maintenance safe room.
- Go down and left to find the Executive Level Access Keycard behind boxes.
- At Factory West, use the keycard to access the F2 lift and ride it up.
- Search the second room with the large table for the shard.
5. Reactor — B1
The walkthrough identifies this as the longest route and says it requires the Grappling Hook. It crosses Waterworks B3 and the Reactor, so follow the switches and key pickup in order.

What to do after finding all eight
The walkthrough says the Data Shards are not missable and can still be collected after finishing the main story. Once you have all eight, take them to the Mainframe in Lower Levels B3, then defeat the final boss again to reach the secret ending, according to that guide.
Epic Games Store independently lists the “Shard Collector” achievement with the description “All Data Shards found.” The listing confirms an all-shards achievement objective, but does not document the locations or verify the secret-ending sequence: End of Abyss Achievements.
