Star Trek Online is a free-to-play massively multiplayer online role playing game (MMORPG) developed by Cryptic Studios and is based on the Star Trek universe created by Gene Roddenberry. The game takes place 30 years after the events of Star Trek Nemesis where the United Federation of Planets and the Klingon Empire are again at war, the Romulan Star Empire is still dealing with loss of Romulus, and the Borg and Dominion are again a major threat.
There are 3 factions you can play: United Federation of Planets, the Klingon Empire, or the Romulan Republic with many customisable species to choose from. Unlike most MMORPG's your character will also control a starship enabling it to explore the vast galaxy.
