Move with WASD or arrow keys, aim with the mouse, and click to shoot. Press R to reload, and number keys (1-4) to switch between picked-up weapons. On mobile, the on-screen joystick handles movement and a touch-to-aim system handles shooting.
Survive each wave to face the next; pick up weapons and ammo dropped by defeated zombies.
Keep Moving - Standing still gets you surrounded fast; even slow circular movement around the map breaks zombie pursuit AI. Reload During Lulls - Don't wait until empty mid-wave; reload between zombie groups when you have a safe moment.
Save Heavy Weapons for Crowds - Shotguns and explosives shine when zombies cluster; using them on stragglers wastes ammo. Use Choke Points - Doorways, narrow paths, and corners funnel zombies into kill zones where one shot can hit multiple targets.
Watch Your Six - The biggest survival mistake is forgetting that some zombies spawn behind you; check your back periodically even when the front is busy.
