Assemble your squad, build synergies, and survive the horde
Fan-made Yet Another Zombie Survivors reference: survivor guides, weapons, synergies, upgrades, maps and achievement tips for the bullet heaven game by Awesome Games Studio.
Yet Another Zombie Survivors (YAZS) is a squad-based bullet heaven roguelite from Awesome Games Studio, released on Steam on August 20, 2026. You command a small team of survivors - a SWAT soldier, a tank, an engineer - that aim and shoot on their own against hordes of thousands of zombies. Your job is moving, dodging, and choosing upgrades as the squad evolves.
Each survivor brings a passive leader perk and a weapon line that evolves through ranks. Synergies between specific survivors trigger bonus effects, permanent upgrades persist across every run, and the prestige system lets you ascend for account-wide power. This guide covers the launch-day blockers: picking the right leader, unlocking all survivors, building synergy squads, and the fastest permanent upgrade order.
