Alpha Protocol, Obsidian Entertainment's upcoming action RPG, is not 'leading' on the Xbox 360, as some have previously presumed. In fact, the game has no lead platform at all.
The game "is being developed for all [platforms] (PC, 360, and PS3) concurrently," Matthew Rorie, Obsidian's Marketing and PR Producer, divulged to PSU earlier today.
Infinity Ward took a similar route with Call of Duty 4: Modern Warfare, and all versions of the game were equal and polished. Infinity Ward was using its own engine for Modern Warfare, however, whereas Obsidian is utilizing Epic's Unreal Engine for Alpha Protocol, which "has a slower development on the PS3 side," according to The Last Remnant developers at Square Enix.
Rorie assured us that all "platforms should wind up seeing the game published on the same day later this year."
