Aliens: Colonial Marines is no longer on Steam

Aliens: Colonial Marines’ is no longer gestating in the stomach of Steam.

The Sega-published game was delisted from Valve’s PC game-distribution service today (via GameSpot). This means you cannot buy the digital version through Steam — although, you can continue to play it as well as uninstall and redownload it if you already own the sci-fi shooter. Additionally, Sega’s 2010 Aliens vs. Predator shooter was also delisted.
