Forget surviving the apocalypse. You’re here to dominate it.
Ground Zero Hero drops you into a radioactive wasteland overrun with mutated creatures. Every enemy you destroy becomes fuel for your evolution. Absorb their remains, stack mutations, and build increasingly powerful and unpredictable combinations until you become an unstoppable force.
Each run is a new experiment. Each build is a new monster.

Every enemy you defeat drops the raw material for your next transformation.
Stack mutations, combine abilities, and create wildly different builds every run.
No two playthroughs are ever the same.
Face massive, screen-filling waves of mutated enemies attacking from all directions.
Each wave escalates. Each night gets deadlier.
Dodge, adapt, and push your build to its limits in pure bullet hell chaos.
