Yet Another Zombie Survivors

BUILD A SQUAD, NOT JUST A SURVIVOR
The zombie apocalypse is a numbers game, so bring your own numbers. Start each run with one Survivor and answer SOS calls to recruit up to two more. Stay solo, run as a duo, or assemble a full three-person squad - the choice is yours.
Every Survivor brings different weapons, abilities, stats, and strengths to the fight. Build around a single powerhouse or combine specialists who cover each other's weaknesses. Certain pairings unlock additional synergies, but there's no single "correct" team you have to follow.

FIND THE BUILD THAT CLICKS
Your squad aims and fires on its own, leaving you to focus on movement, positioning, dodging, and the decisions that shape your run. Upgrade weapons, choose abilities, evolve them in different directions, stack items and badges, and build around damage types, effective range, and each Survivor's strengths.
The real fun begins when those choices start feeding into one another. Cooldowns shrink. Effects spread. Projectiles multiply. A build that looked merely sensible five minutes ago can suddenly turn the entire screen into a very loud argument for overkill.

SIMPLE CONTROLS. SERIOUS MAYHEM.
YAZS is easy to pick up, but the Horde won't politely wait for your build to come online. Dodge attacks, rescue survivors, chase supplies, and react to threats coming from every direction. Auto-aim keeps the action accessible, while manual aiming lets you take control whenever you want to squeeze more out of your weapons or focus down a priority target.
Guns, flamethrowers, blades, explosives, drones, and other increasingly unreasonable tools of survival tear through fully 3D hordes with blood, ragdolls, and screen-filling effects. It's dark, hectic, and deliberately satisfying.

PLAY FOR A RUN. STAY FOR THE EVENING.
Pick the experience you're in the mood for. Fight through standard runs, tackle wave-based Extermination, survive escalating pressure in Endurance, chase ridiculous builds in Infinite, test yourself in One Hit, or race to become strong enough for the bosses waiting in Boss Rush. Difficulty levels and optional challenges give you plenty of ways to make the Horde meaner when you're ready.

GROW STRONGER BETWEEN RUNS
Survival is only the beginning. Develop a general skill tree and separate progression for each Survivor, unlock new weapons, abilities, evolutions, items, and badges, and keep experimenting as more options enter the pool. If a setup stops being fun, change direction and build something else.

EVERY ARENA WANTS YOU DEAD
Each area brings its own enemies, layout, and hazards instead of serving as a different backdrop for the same fight. Trains thunder through Dead Terminal. Bio Lab squeezes the battlefield with toxic danger zones and decontamination cycles. Bosses bring threats that demand more than simply mowing down whatever happens to be closest.

MEET THE SURVIVORS
Between runs, return to the Survivors' Base and meet your squad away from the battlefield. Follow character stories and missions, listen to conversations and radio chatter, and discover more about the people — and the world — behind the apocalypse.
None of that gets between you and the action if you don't want it to. If you came here only to turn zombies into statistics, you can get straight back into another run.

ONE MORE RUN
YAZS is built around that moment when a team, a handful of upgrades, and a questionable plan suddenly click into something absurdly powerful. Then you raise the difficulty, swap the leader, change the squad, chase a different synergy, and try to break the game all over again.
