All eight Chained Beasts
Checked 2026-10-18
The launch announcement says eight beasts, with variants and cosmetics. Official Steam achievements name Lion, Eagle, Bear, Panther, Ibex, Rhino, Monkey, and Wolf. This reference does not supply unverified starting stats or individual unlock requirements.
Source note: the Steam achievement page saved on 18 October 2026 publishes display names and api_name fields together. It directly confirms Free as an Ibex as WinRun_Stag; this is not an inferred pairing. The percentages below remain the separate 17 October 2026 global API snapshot. No beast kit was play-tested for this page.

Variants and progression
The 29 May 2026 demo announcement says fighting with a beast earns XP that unlocks variants. That update added Ibex and Rhino and reworked the existing beasts. The launch announcement distinguishes eight beasts from their variants and cosmetics; variants may have different stats and abilities.
The saved sources do not provide a complete per-beast starting-perk table, individual unlock conditions, or a tested variant comparison. Beast XP progression should not be confused with the shared training bar described in the beginner guide.
Bestiary is the official achievement for unlocking all beasts; its historical player unlock percentage was 0.1% on 17 October 2026. That figure does not reveal unlock order, explain why players lack an achievement, or identify a secret character. A beast’s win-achievement percentage does not tell you its share of runs or its success rate.
