The other games had better art and graphics, at least in my opinion. The character models and animations just look strange and unnatural, especially when you're inside a house. Not a bad game, just kinda disappointing.
Horribly unbalanced. The game can be fun, but beginning players are at an incredible disadvantage. The game also encourages the player to drop into a crawl whenever he gets into a conflict, meaning that the game often dissolves into prone groups firing wildly at each other.
