Steam’s global percentage API returned 40 achievement IDs on November 10, 2026. Percentages change as players unlock achievements. Steam’s newer community interface showed different percentages during our check, so these figures are specifically the API snapshot, not a guarantee of the live display. Hidden achievements may contain story spoilers.

Names and descriptions below come from the English Steam achievement page metadata. BIOPOD is an internal API identifier: the page metadata associates it with a hidden name and condition, but its public display name and condition remain unconfirmed here. Hidden entries contain spoilers.
