'Aliens: Colonial Marines' and AvP 2010 removed from Steam

Aliens: Colonial Marines and Aliens vs Predator (2010 version), the two xenomorph-based games from Sega have been removed from Steam for direct purchase.

The possible reason for the removal is the expiry of licenses, which is a regular cause of games being unavailable for direct purchase from Steam. The two games however, can still be bought in physical form. Digital stores like Green Man Gaming offer both that can still be activated on Steam.

Well, neither of the two games had a good response from the customers and their removal from Steam will not disappoint a large number of people.
