The short answer
Version 1.0 is the full-release state of YAZS. It adds the ninth Survivor, the fifth arena, Boss Rush, Camp and mission systems, rank 5, more synergies, 21 new items, and 88 new achievements.
01 / Full release
YAZS 1.0 marks the end of Early Access.
Yet Another Zombie Survivors officially left Early Access on August 20, 2026. If you are returning to the game, check the dates on older roster, unlock, build, and balance guides because pre-1.0 information may now be out of date.
02 / New Survivor & arena
Ranger joins the roster. Bio Lab becomes the fifth arena.

In version 1.0, Infinite Mode now correctly unlocks after you survive 30 minutes in Endurance. Older unlock guides may describe the pre-1.0 behavior.
