Not exactly an intense (or hard) FPS, but still can be fun.
Now, the game is set up very cool. The map where you choose where you want to go is fun. Also, character classes add a little role-playing element to it. The only bad part is, it doesn't really work. You go to an enemy camp and try to take it over, while 5 guys burst out of thin air and shooting you!
Multiplayer, however, CAN be fun, intense, and there are some good team players.
Overall, this game is not what hardcore gamers are looking for. It's more of a go over to your friends house to play every once and a while game.
