Current total and version
The full-game Steam achievement page listed 37 achievements when reviewed on September 14, 2026. The store page and Exophase showed the same total, and the official 1.1.2 notes explain that a new difficulty-related achievement was added. Older lists showing 36 belong to an earlier version and should not be merged with today’s total. Because Steam’s list is dynamic, the number should be checked again after another patch.
Chapter and collection goals
Exophase’s catalogue names chapter achievements through chapter nine, consistent with the chapter navigation in two separate full-game videos. Steam also lists Craftsman for assembling an old gun, The Collector for obtaining extra weapons and Omniscient for reading files. These names show categories of objectives without revealing every hidden requirement or the location of every collectible. A nine-chapter outline is supported, but this page does not invent a chapter-by-chapter achievement checklist.
Combat and difficulty goals
The official list includes Seasoned Sheriff, linked to a Hardcore completion goal in the research. Patch 1.1.2 introduced a new difficulty mode and a related achievement, which explains why older achievement totals differ. A video author describes Sweaty? as breaking a brute’s armor before the kill; the Steam public description is hidden, so that exact condition remains 待确认. Do not apply a video author’s interpretation to every difficulty or platform version.
Hidden conditions need care
Some Steam achievements have hidden descriptions on the public page. A secondary database may display more text, but it is not an independent proof that every condition still behaves identically in the current build. The research did not verify all 37 by triggering them in game, nor did it establish recovery steps for missable goals. Treat any precise hidden trigger beyond official visible wording as 待确认.
Prologue versus full game
The free Prologue is a separate Steam app with its own five-achievement list. Those five are not a subset that can be added to the full game’s 37 to make one completion target. Check the app identifier before following a guide: 2918090 is the full release and 3642660 is the Prologue. The research did not establish how Steam achievements map to PlayStation trophies, so cross-platform completion equivalence is 待确认.
