I really wanted to like this game, but it is just too frustrating. First, controls are all screwy. Why does E change weapons? Why can't I use the scroll wheel? Why does mouse 3 zoom in, and not mouse 2? It's almost a requirement to change the default controls of the game. Second, Vegas? Really? Why would terrorists invade Las Vegas? That's never really explained. Third, the 20 minute shootouts get really old. Lots of rooms have ample cover for the terrorists to hide behind, but not you or your teammates. You can take cover and order your teammates to take cover, but you'll still have to heal your teammates repeatedly. That gets to be a chore quickly. Also, in certain rooms, there will be a lot of annoying obstacles, such as plants and railings, that block your vision and firing path in the worst possible spots. Because of these obstacles, and the annoying game mechanics, expect to die a LOT. Again, wanted to like this game, because the whole "shootout" style of gameplay is really fun. This game somehow managed to make it plain annoying.
