Tribes: Ascend is going free-to-play, but may be straying away from Xbox Live Arcade. The game is set for a fall release, but Hi-Rez Studios’ Todd Harris told Joystiq that they’re “focused on delivering Tribes: Ascend for PC only.” When asked about the original plans to bring the game to XBLA he stated that “an eventual XBLA version, and even PSN version, is not out of the question but neither will be this year.” Doesn’t sound overly promising, but in the meantime we have the incredibly awesome Section 8: Prejudice which more than fulfills any large scale Sci-Fi shooter needs.
