Quick answer
There is not enough official evidence to publish a definitive multiple-endings tree. The current community walkthrough describes one campaign conclusion, while the public store and achievement list do not document alternate-ending conditions. That makes “one ending” a useful working answer, not a permanent guarantee.
Before the apparent finale
- Confirm the game is updated to version 1.03.
- Preserve the newest valid checkpoint and avoid overwriting every earlier recovery point if the interface permits a choice.
- Finish unresolved tool, collectible, and achievement cleanup before crossing a clearly final transition.
- Record any explicit choice and the resulting achievement rather than inferring causation from a cutscene alone.
Why the answer remains mixed
An achievement inventory can reveal completion categories, but absence of an obvious alternate-ending achievement does not prove no alternate state exists. A community walkthrough can document one completed route without exhaustively testing all branches.
This page will remain marked mixed until an official developer statement or independently reproduced route documents the ending structure. It does not invent a “true ending,” hidden morality system, or choice requirement.
