Summary: One day, it was near my best friends b-day, so i was search for the perfect game for him. Then i found this game. I bought it, and played it right away. When i started playing, the game was impossible to stop playing. This game has all types of futuristic weapons you can use! And yes, there is a co-op mode. The 4 characters you start out with is Tactical, heavy, trooper, and my personal favorite, Jet. This characters have their own special ability!
