Intruder is a tactical multiplayer game currently in very limited alpha. Only a few people get early access, and more keys are on the way. The best place to keep track of sales is the Superboss Twitter account. It’s lots of fun.
It's a tactical simulator like SWAT or Rainbow 6, but with physics, and a bunch of fun features like being able to feign your death.
Features:
Team-based stealth multiplayer: Guards
vs. Intruders.
Immersive FPS: climb, crouch, crawl, and
swim through the environment.
Use gadgets to trick, trap, distract and
outsmart your opponents.
Eavesdrop on the opposing team with
spatial voice chat.
Truly interactive buildings with working
security cameras, sliding windows,
ventilation shafts, and elevators.
Stealth-based missions with multiple
objectives and escape routes.
Regular updates and new features based
on community feedback!
