4.5 stars excluding xen.
4 stars with it.
If you really like the source engine and seeing the limits of it, as well as stuff like source platforming, and just playing a shooter that feels like you're on drugs, this game's pretty good. There's also an incredible attention to the detail throughout the game, just explore the opening act before the actual combat sections begin and you'll found countless details. Unfortunately, I think the game loses itself and what makes it so much fun in Xen.
