With Interstellar Marines still on Early Access on Steam, it is still currently in heavy development and still needing the support from the fans during the process, in order to bring everything fans want, but also bringing the game closer to the dream updates into the near future. “Co-op is one of the central pillars of the game, and is a big part in providing players with an outstanding tactical experience in as realistic a manner as possible,” mentioned the creative director on Interstellar Marines, Kim Haar Jørgensen. “The co-op demo we will be showing at Alienware’s booth is an early slice of what we are working on. This is the first chance we have to present this early version of co-op to our players and we are eager to hear their feedback. After the release of Project Co-op in September we will continue to enhance and refine the co-op experience until it reaches the lofty heights we are aiming for.”
