About OmniGun

Announcing the OmniGun, a powerful new weapon by Kill Inc designed to fire anything as ammo.

Full production is underway in our massive fully automated facility that has been certified as unlikely to experience an AI uprising. . .

Physics Based Mayhem

OmniGun features kinetic physics based FPS combat with highly reactive enemies allowing you full creative freedom.

  • Knock enemies down by shooting their legs
  • Sever limbs with bladed weapons
  • Grow and shrink enemies
  • Manipulate gravity as enemies float harmlessly away
  • Freeze enemies solid with cryo weapons, or stun them with electricity.

Mutate Your Arsenal

Every ammo type has a set of possible mutations allowing you to power up and customize your OmniGun’s potential. Cutting lasers become death rays, frag grenades into artillery shells. Experiment and discover anything from cannon balls, to harpoons, to exploding shotgun shells to black holes.

Endless Roguelike variety

Fight your way through procedurally generated floors as you face off against a full arsenal of varied enemies, bosses, and environmental hazards. Each run presents a unique set of challenges and threats to overcome!

Key Features

  • Physics based damage system accounting for kinetic, thermal, electric, scale, and gravity based weapons
  • 100+ hand crafted ammo types to find and mutate
  • Procedurally generated floors and run paths for maximum replay value
