Following some early warnings about the operation, Sega has officially acknowledged the existence of espionage RPG Alpha Protocol. Obsidian Entertainment (Knights of the Old Republic II and Neverwinter Nights 2) is developing the game, which is expected to release on Xbox 360, PS3 and PC in early 2009.
Sega currently has no images of the game to share. All we know is that you play as a "young agent cast out by his government" and "Alpha Protocol embraces everything [Obsidian] enjoy[s] about making RPGs from a fresh perspective." So, the best current guess would be ... Mass Effect with spies?
