Sega still hasn't set an official release Aliens vs. Predator, but that isn't stopping them from releasing all kinds of clips promoting the game. You can check out the latest, a developer diary entitled Heritage, after the jump.

This clip is very cool because it highlights how this new game expands on Rebellion's 1999 Aliens vs. Predator title. I never got a chance to play Rebellion's initial release, but it invariably turns up on any list of "really scary videogames". It looks like the new title is set to join those same ranks.

Aliens vs. Predator is a first-person shooter with stealth elements that allows players to take the role of Aliens, Predators, and Space Marines at various narrative junctures. The title is slated to appear on the PC, Xbox 360, and Playstation 3 sometime next month.
