The game was announced back in 2010 and was being overseen by German publisher Gameforge. Gameforge have decided to shut down production on the free-to-player browser-based MMO after it was unable to find new partners. Gameforge said in a statement:
"Since autumn 2011 we made many efforts to find a publishing and marketing partner for Star Trek: Infinite Space. Unfortunately, our efforts were not successful. So we have decided with a heavy heart to finally abandon the project Star Trek: Infinite Space. The discontinuation is very regrettable. Unfortunately it happens from time to time that a good concept for a game cannot be implemented as originally planned."
Back in November the German company cut 100 employees from its 450 strong team, and reported that it would struggle to release the game without a co-publishing deal. However, Namco Bandai is set to launch a co-op third-person shooter based on the new Star Trek movies next year. So there is still hope for the franchise, just not for this particular game. Live long and prosper, Gameforge.
