Only 3 levels though??? well, it's like having an unlimited ammount of quarters for this game by paying a one-time fee. the Game is really fun, and I bought this in Wal-mart with the Perfect Shot, I own another Shooter: The Conduit, and this game is about equal to that one. The game is more fun than the Conduit, but Ghost Squad only has 3 levels. I finished the campaign in 45 minutes. However, there is so much customizing and weapons that to get the game's full experience, you'll spend 50 hours playing. great shooter with or without friends.
