End of Abyss achievements and completion checklist

Completionist covers four Logbook categories

Creatures, Notes, Data Shards and Codes each have their own collection goals. Completionist brings all four together. If the overall achievement is missing, compare those categories separately instead of repeating your whole route.

Keep the Scanner involved in exploration, and record a named target in your return notes when you cannot complete it yet. The checklist records your own assessment; it does not claim to inspect your Epic profile or game save.

One upgraded weapon and all upgraded weapons are different goals

Power Up is for fully upgrading a weapon. Super Power covers every weapon. Fully Suited Up instead concerns maximum Suit Power. Planning these separately prevents a single finished gun from feeling like the whole equipment category is done.

Use the weapon location lookup to check for a missing gun and the save-and-death guide when balancing permanent upgrades against consumable ammunition. All six guns remain obtainable after the story, but that does not establish that every other achievement is unmissable.

Check rooms and shuttle stations independently

Master Explorer requires every room; Shuttle Network Restored requires every station. The map can expand both from exploration and from map stations. For a room goal, check entry and coverage rather than assuming a shuttle unlock finishes the sector.

Organize the remaining trips with map and backtracking. If a power door is blocking a completion run after an interrupted node sequence, check the door fix before discarding the save.

Keep specific combat conditions in view

These are conditions to plan around, not location promises. Keep enough resources for the attempt you intend to make, and do not assume a failed fight restores a used grenade. The tracker deliberately does not invent hidden-achievement solutions or collectible coordinates.
