Astronaut Geometry

Astronaut Geometry is a 3D co-op game where you float through an alien-infested spaceship and clean it out with foam. Everything is built from simple shapes.
This game features:
- Newtonian rocket-pack flight and a foam sprayer with swappable nozzles
- a new randomly generated ship every job, with nests, sleepers, hull breaches and a queen
- job kinds: rooms, sweep, express, rescue and queen hunts, with hazard levels and mutations
- power-ups, a company account, ranks and a locker of upgrades
- couch split screen for up to four, online crews, and computer crew to fill empty seats
Plays in the browser with keyboard and mouse, a controller, or touch on phones and tablets.
