Two of Sega's Alien games are no longer available for purchase on Steam: Gearbox Software's Aliens: Colonial Marines and Rebellion's Aliens vs. Predator. Their removal on the last days of 2014 could mean the end of Sega's license to sell those titles through digital services like Steam.
Aliens: Colonial Marines is still available for purchase through sites like Green Man Gaming and Amazon, through codes that redeem on Steam. The PC version of Aliens vs. Predator appears to have been recently removed from Green Man Gaming, though Colonial Marines is still available. Other Alien games, including the Rebellion-published Aliens vs. Predator Classic 2000 and Creative Assembly's Alien: Isolation are still available on Steam.
Colonial Marines and Aliens vs. Predator are still available to download on PlayStation 3 and Xbox 360 via their respective online stores.
Other licensed games, including Activision's slate of Marvel titles — the Deadpool, X-Men and Spider-man games — have been delisted from Steam, PlayStation Network and Xbox Live in time with the new year. Two Activision-published titles, Family Guy: Back to the Multiverse and Ice Age 4: Continental Drift: Arctic Games, were recently delisted from Steam.
We've reached out to Sega, Gearbox Software and Rebellion Developments for more information on the Alien games' removal.
