Aliens: Colonial Marines has recently resurfaced.
Originally slated to arrive on the Playstation 2 back in 2001, being developed by Check Six Games then, production was cut short some time prior to release and hadn't been heard from since. Currently the game is in the hands of Gearbox Studios and we're looking to see a release sometime next year. Hopefully in the early months of next year. Here's a glimpse from E3.
I salivate in anticipation.
