The basic idea was good, the graphics are okay for a game from 2010 and the universe of the series is rather respected. However it is essential to create a Steam account to play this game (Steam is a DRM). The multiplayer mode is very poorly done (not present server browser so you hassle to find parts) and there are very few players (not even a dozen ...). The solo is as Predator and Alien but it is excruciatingly boring as Marines. Note that the classes Predator, Marine and Alien are very unbalanced and it shows a lot in the multiplayer mode (it is almost impossible for Marines to win against an Alien or Predator). The difficulty is sometimes wrong dosage (too complicated game) and the gameplay is sometimes strange (some passage are impossible to achieve the first time that we play because every enemy hit us. We must remake the passage several times to succeed ). If you are a big big fan of the Alien series, this game can be interesting but the rest go your way.
