Star Trek D-A-C - PC and PlayStation Network versions to arrive in November announces a November release date for the Windows and PS3 editions of Star Trek D-A-C, the top-down space shooter that's currently only available on the Xbox 360. Here's a bit from Starfleet Command on this one:

Star Trek: D-A-C allows fans to directly control a variety of ships and pitch battles between Starfleet and the Romulan Empire. Up to 12 players can compete in thrilling team combat. There are three game play modes: Single player, online multiplayer and online co-op. For each mode, there are four different game types - Team Assault, DeathMatch, Conquest, and the all-new Survival mode, pitting players against increasingly overwhelming waves of enemies in order to set the record for survival time.
