It's never been made clear just how far Obsidian got with Aliens RPG, a project that started back in 2006 and was then canceled in June of last year. If alleged footage from the uncompleted game is any indication, there was more than a solid foundation laid down. The brief snippet of supposed gameplay paints Obsidian's game as more of a third-person shooter than a traditional RPG -- though we're quite used to that sort of thing by now.
Head past the break to see the footage, but make sure you turn up your brightness before doing so. This video is dark.
