Games like interstellar marines

Interstellar Marines is a science fiction first-person shooter video game being developed by indie studio Zero Point Software. It was added to Steam Greenlight on 3 September 2012 and later released on Steam Early Access on July 2, 2013. Updates are generally released every six to eight weeks with some larger sprints.

Interstellar Marines is being developed in four acts, formerly planned as individual titles. The first act, code-named "Prologue", is currently in development and takes place in a future military training facility that will stage multiplayer, single-player, and cooperative training scenarios. Multiplayer was the first feature of Prologue to be built, doubling as both a tech foundation for future co-op missions and as a playable Early Access release on Steam. The first co-op mission, titled The NeuroGen Incident, was released on September 26 which built much of the technology needed for future co-op campaigns.
