Couch Co-op Survival Mayhem

Box Zombies is a chaotic, easy-to-learn, co-op survival game for 1-4 players. Fight through massive zombie hordes, explore both randomly generated and handcrafted maps, and build defenses to survive escalating day/night cycles.

"The kind of game where everyone's laughing, someone's yelling, and nobody wants to stop playing."

The shared camera is the heart of the game: every player shares one screen meaning that every discovery, narrow escape, and desperate last stand plays out together.

Key Features

Built for Co-Op: Up to 4 players on one shared screen. The camera keeps everyone together, so cooperation is survival. But watch out for stray bullets and bouncing grenades!
Fresh Every Run: Randomized maps, weapon spawns, and powerups keep every session fresh. Every 3 rounds, a whole new map loads in and the exploration starts again.
Massive Hordes: Day/night cycles shift the pacing and tension. Every 3rd round brings a Mega Zombie wave with bigger, tougher enemies that grow in number each time they appear. Survive long enough and the screen becomes pure chaos.
14+ Weapons and Defenses: Discover rifles, explosives, sentry guns, barricades, and more. Stock up on ammo before the round ends or hope your favorite weapon spawns in the next map.
20+ Unlockable Characters: Unlock a diverse roster of characters through in-game challenges. No paid unlocks or loot boxes. Every character earned through skill.
Party Ready: Simple controls mean anyone can jump in and have fun no matter their skill level. Designed for game nights and drop-in party play.
