How to Play & Controls

Your objective is simple on paper but brutal in practice: survive as many waves as possible while racking up kills and points. Each wave throws more zombies at you, and tougher variants start showing up as you progress. You'll need to move, aim, and reload without getting cornered.

Desktop controls:

• WASD or Arrow Keys — Move your character around the map
• Mouse — Aim your weapon
• Left Click — Fire
• R — Reload
• Number Keys / Scroll — Switch weapons

Mobile controls: Use the on-screen joystick to move and tap the fire button to shoot. Aiming is handled automatically or via a second touch zone, depending on the version. It's surprisingly smooth once you get the hang of the thumb layout.

Key Features

• Endless Wave Survival: Each round escalates in difficulty, testing how long you can last under pressure.
• Weapon Arsenal: Unlock and upgrade pistols, shotguns, rifles, and more as you earn points.
• Multiple Zombie Types: From slow walkers to fast sprinters and armored brutes, variety keeps you on your toes.
• Instant Browser Play: No downloads required — perfect for quick sessions on unblocked games platforms.
• Score Chasing: Compete against yourself or friends for the highest kill count and survival time.

Pro Tips & Strategies

1. Keep moving, always. Standing still is a death sentence. Circle-strafe around zombies and use the map's edges to funnel enemies into a manageable line rather than getting surrounded.

2. Aim for headshots. Headshots deal bonus damage and save ammo. Against fast zombies, a clean headshot is often the difference between survival and a game over screen.

3. Invest in the right upgrades early. Don't blow all your points on a flashy weapon right away. Boost your fire rate and magazine size first — sustained damage beats raw power when the horde gets thick.
