Star Trek Online isn't a pleasant place. It's filled with many threats, some familiar to players already (the Borg and the Voth spring to mind) and others heretofore unseen. Delta Rising is going to bring players into contact with this violent region of space, and the newest trailer for the expansion shows that players will find no shortage of enemies -- including many races that had faced off against the USS Voyager years earlier.
Players who watch the trailer can catch several familiar locations and enemies from Star Trek Voyager, including some minor enemies such as the Vaadwaur. Click on past the break to view the trailer in all its glory. It doesn't have a whole lot of story provided just yet, but it serves as a clear indication that the quadrant hasn't gotten any friendlier since the last time Starfleet visited.
