The tactical FPS Interstellar Marines has received a significant update today, which adds co-op gameplay to the game.
The NeuroGen Incident will allow you and three friends to play through a pivotal event in the Interstellar Marines universe. The mission ties directly into the single player and co-op campaign, which will be added to the game in the future.
Interstellar Marines is an Early Access game on Steam, and is being developed using the Unity engine. Check out the trailer from PAX 2014 below to see the co-op gameplay in action.
