About the Game

The undead never stop coming… but neither do you!

ZK1L4 is a Left 4 Dead–style roguelike survival shooter where every run tells a different story. Fight through five handcrafted apocalypse scenarios, unlock devastating skills, and push forward toward a final escape… or die trying.

Fast, brutal, and endlessly replayable: ZK1L4 blends cinematic zombie survival with roguelike progression and chaos. Think Left 4 Dead meets a bullet-heaven roguelite.

8 Survivors

Choose from 8 unique survivors.

60+ Skills

Stack 60+ active and passive skills to create broken, beautiful chaos:

  • Critical hit builds

  • Lifesteal monsters

  • Summoners

  • Explosive on-hit effects

  • Run-defining synergies

Your choices matter. Your build defines how you survive.

2 Players Couch Co-op Chaos

Bring a friend, you’ll need them.

Fight side by side in local 2-player co-op, combining builds, saving each other from the swarm, and turning desperate runs into heroic escapes.

5 Unique Scenarios

Each map is a chapter in the apocalypse:

  • Unique layouts

  • Unique mechanics

  • A clear narrative goal

You’re not just surviving! you’re moving through a collapsing world toward the truth behind the outbreak.

30 Collectibles

Discover 30 lore collectibles scattered across the world.

Each one reveals what happened before and during the zombie apocalypse: survivors, experiments, betrayals, and the price of failure.

The Enemies

The swarm is endless… but not all zombies are equal.

Face terrifying enemy types:

  • Sneaky – Silent, deadly

  • Fatty – Slow, but explosive

  • Fast – Relentless hunters

  • Tanky – Brutal damage sponges

  • Goliath – A walking apocalypse

And now… a new threat:

The Golden Sir

A rare elite enemy that drops powerful rewards if you can take it down.
High risk. High reward. Total chaos.
