With the North American and European launch of Cryptic Studios's Star Trek Online this week, publisher Atari announced that the subscription-based PC MMORPG has already attracted over one million registered accounts.

Atari and Cryptic have aggressively courted early subscribers in the past several weeks with promotions like discounted lifetime and year-long subscription plans available for a limited time. The companies also teamed up with cable network Syfy to offer an exclusive digital download bundle through the channel's site and to run a two-day marathon of Star Trek episodes this week.

Based on the popular science fiction television series (taking place in a time frame beyond the currently released films), Star Trek Online enables users to command starships under the United Federation of Planets or the Klingon Empire. They can take on missions, explore planets, upgrade their ship, recruit characters for their crew, battle other starships, and more.

"After much anticipation, we are pleased to present Star Trek Online to fans and gamers nationwide," said Atari CEO Jeff Lapin. "Throughout the last four decades, Star Trek has been a mainstay in pop culture, influencing legions of 'trekkers' through television, film, and more. We expect Star Trek Online to give fans and gamers an unprecedented Star Trek experience."
