ASPIS Wiki — Soviet Horror Guides, Endings & Achievements

The developer's own site gives the full name as Autonomous System for Predicting Historical Events. In the fiction it is a Soviet research machine built to model the past. The game is also written as АСПИС in Russian. Official material does not expand the acronym any further, so any other interpretation you see online is fan speculation rather than a documented second meaning.

Official material does not describe a save menu. Players on the Steam forums report that the pause menu has no save option and that autosave timing is not explained, so treat the game as checkpoint-driven until the developer documents otherwise. If you are testing a route or an achievement, finish a story beat before closing the game rather than assuming you can reload a manual slot.

The PEP-01 captures X-spheres, interacts with Energy X and opens astral windows between layers of reality. In practice you relocate energy or objects, change which layer you are standing in, and then take a path that only exists from the other side. The game is built around spatial relocation, not code guessing, so look for what you can see but cannot reach before hunting for a keypad.

No. Official text says the Guardian cannot simply be shot, and the chase design is about keeping distance, breaking line of sight and using doors and corners. Ammunition is scarce and found in the environment, so spending it on the Guardian is a waste. Players report that hiding does not always break pursuit, so keep moving until the encounter music and behaviour actually change.

Two. Official material describes one choice and two endings, and the achievement list names the branches as Let Go and World on Fire. There is no announced third, secret or post-credits ending. Because both achievements depend on the same final decision, you cannot earn the pair in a single run unless you replay the closing section and choose the other option.

Several are tied to specific moments. I Will Stay Here is a hidden flag that asks you to remain and listen to Maria right after your first meeting, and the ending pair requires two different final choices. Story achievements such as Management Approves unlock automatically if you finish the prologue and re-enter the ASPIS system, so the main risk is walking past optional scenes rather than failing a skill check.

The Steam announcement feed and the developer's Telegram channel are the two official sources. ASPIS launched on October 23, 2026, and the first weeks are likely to bring technical fixes, so a dated updates page is more reliable than a static guide. If a claim appears only in a Steam forum thread, this wiki labels it as a player report rather than a confirmed patch note.
