At the Eurogamer Expo -- in Europe! -- Team17 has revealed its plans for the episodic structure of its upcoming downloadable title, Alien Breed Evolution. It was previously revealed that the game would be released in three separate episodes, and now Team17's John Dennis explains that each episode will contain a prologue and five levels that are "much larger than they should have been." In addition, each episode contains two major "set pieces" -- large scripted events -- as well as two boss battles and a multiplayer level. Each episode should last five to eight hours.

The first episode of Alien Breed Evoluation should release fairly soon, as it was originally slated for "around October." The XBLA version will enjoy an unknown period of exclusivity before the PSN and PC versions are released.
