I really love this game even in spite of the snow yetis. This is the game that introduced the now standard feature of weapons that evolve with use. The game's just bigger in scope compared to the first and the shooting is improved with some much needed features like the ability to strafe while shooting. This game also starts the tradition of a hidden museum that features developer commentary and content that was cut from the game. It's a lot of work, but I wish more games would do something like this.
