Build Your Loadout. Outplay the Swarm. Thrive in the City.

Decades after a catastrophic event wiped humanity off the map, mutated bugs rose from the ruins and turned entire cities into their hives.

You are a mercenary-for-hire, one of the rare survivors trained to breach the infested city walls and bring back what everyone else fears to touch: bug parts. Valuable, volatile, and vital for making a profit in the new world.

⚔️ Fast, Hectic, Wave Combat

Dash, shoot, blast, or slice your way through escalating swarms in quick waves.
Find weapons, merge upgrades, and create powerful builds as you fight to survive long enough for extraction.

Auto-firing and manual-aim hybrid combat
Runs designed to be quick, chaotic, and endlessly replayable
Hundreds of items and endless synergies

🎒 A Smarter Backpack Means a Stronger You

Your backpack is your build.
Every weapon, trinket, attachment, and oddity fits into a grid-based inventory where position, adjacency, and orientation matter.

Discover items with unique shapes and effects
Build insane synergies based on placement
Merge items into new and powerful tools

Pack smarter. Live longer.
