End of Abyss Scanner Guide: How Scanning Works and Why It Matters

The scanner is the gadget that turns End of Abyss from a shooter into an investigation. It is a dual-mode tool you swap between with the d-pad, it draws instant Metroid Prime comparisons from press coverage, and it touches nearly every system in the game — exploration, combat prep, map knowledge, even achievements. Here is everything confirmed about it from pre-launch coverage, with the unknowns flagged until October 1, 2026.

What is the scanner in End of Abyss?

A dual-mode gadget, swapped between its two modes with the d-pad, that reads the world around Cel. Press coverage has reached for Metroid Prime as the comparison since the reveal, and the lineage shows: one mode sweeps walls and the environment, the other sweeps enemies. It is not a passive minimap decoration — scanning is how the game communicates its hidden layer, and hands-on coverage treats it as central to progress rather than optional flavor. If you are new to the game overall, start with the beginner guide for the full picture.

What does wall scanning reveal?

Weak points and hidden spaces. Sweeping the environment exposes structural weaknesses — the kind you can then act on with explosive charges — plus concealed spaces you would otherwise walk straight past. In a Metroidvania where new equipment opens sealed areas and shortcuts are worth their weight in shells, the wall mode is how you find the facility’s real floor plan. Pair it with the map guide to keep track of what you have opened and what is still sealed.

What does enemy scanning give you?

Behavioral and tactical data — what a creature does and how to answer it. Where the wall mode maps the level, the enemy mode reads the threats: attack behavior and tactical guidance for the creatures in front of you. The headline use is the split warning: some enemies split into multiple threats when damaged, and the scanner tells you which ones before you commit ammunition you cannot spare. How to act on that data — roll spacing, weapon choice, target priority — is covered in the combat guide.

Does the scanner mark locked doors on the map?

Yes — automatically. Locked doors you encounter get auto-tagged on your map, which turns “where was that sealed door?” from memory work into a checklist. That matters because backtracking is structural in End of Abyss: permanent upgrades and new equipment open areas that were sealed on your first pass, and the map tags are how you route those return trips instead of wandering the facility hoping to recognize a corridor.

Does the scanner help when you’re stuck?

Yes — it gives hints when you do not know where to go next. The scanner doubles as the game’s anti-frustration layer, nudging you toward points of interest when progress stalls. Between wall sweeps, automatic door tags, and the hint system, the scanner effectively sets your exploration difficulty: players who scan constantly spend far less time lost than players who treat it as an afterthought.

Is there an achievement for scanning everything?

Yes — a full-scan achievement. Scans feed a codex system that logs everything you have examined, giving completionists an explicit goal: scan it all. One comfort in a punishing game — scans persist through death (opened doors and completed scans stay when you respawn), so codex progress is never lost to a bad fight.

How does the scanner change combat?

It moves the winning decision to before the first shot: scan to learn the threat, then pick the right tool. Against splitters, the scan prevents multiplying enemies mid-fight. Against unfamiliar creatures — grabbers, dog-like hunters, the bipedal monstrosities — it tells you whether this is a pulse pistol fight or a moment to break the shell discipline and spend shotgun shells. Pre-scan, commit, and keep flares in mind for when the read comes too late.

What don’t we know about the scanner yet?

The fine print. Pre-launch coverage confirms the two modes, the codex, and the full-scan achievement, but not the complete scanner UI, how many entries the codex holds, or whether any scans can be missed past a point of no return. None of that is public yet — we will verify it at launch on October 1, 2026, and update this guide alongside the weapons overview.
