ZK1L4

ZK1L4 is a roguelike survival shooter in which you fight through five handcrafted scenarios during a zombie apocalypse. Each run unfolds differently as you build up skills and push toward a final escape—or die trying. The scenarios have distinct layouts and mechanics, with narrative goals that take you through a collapsing world toward the truth behind the outbreak.

Survivors and skills

Choose from eight survivors. Across a run, you can combine more than 60 active and passive skills, including critical-hit builds, lifesteal, summoners, explosive on-hit effects and synergies that can define your build.

Local co-op

Two players can play together in local co-op. You combine your builds, fight side by side and save each other from the swarm as you try to escape.

The apocalypse

The five scenarios each form a chapter, with a unique layout, mechanics and narrative goal. Thirty lore collectibles scattered across the world reveal what happened before and during the apocalypse, including stories of survivors, experiments, betrayals and the price of failure.

The zombie swarm includes Sneaky enemies, which attack silently; slow, explosive Fatty enemies; relentless Fast hunters; damage-absorbing Tanky enemies; and Goliaths. A rare elite enemy called the Golden Sir can also appear, dropping powerful rewards if you defeat it.
