Yet Another Zombie Survivors 1.0 expands the available class choices, and this guide ranks them by their usefulness in the current game meta. It places Medic, Tank and Swat in the top tier because they offer reliable healing, survivability, area damage and boss control, making them especially valuable for demanding runs.

– S-tier: Medic provides sustainable team-wide healing; Tank levels quickly, has solid health and area damage; Swat combines strong damage, crowd control and turrets for elites and bosses.
– A-tier: Ghost excels at rapidly clearing enemy waves but struggles against bosses; Engineer offers the strongest crowd control but lacks sufficient damage at higher difficulties.
– B-tier: Huntress has excellent range but inconsistent abilities unless heavily upgraded; Pyro is fragile, has mediocre weapons and lacks dependable area damage or crowd control.
– The Ranger has not yet been assessed by the author.
