I played this a year or two ago when it was still just an indie game made by some guys in a house or whatever. It was fun then and its fun now.
It's a great little pick up and play game that requires little real thought and is just some mindless fun for a few minutes when your bored. I thoroughly love it as well as it's graphics. There is only one musical track that loops constantly but that can be turned off if it annoys you as it does me.
Looking forward to playing this with friends.

A lot of fun and free2play. What more do you want?

DO NOT! Buy this game. You want to play as Predator? The training at the start is 12% of the entire Predator campaign. The game is completely unbalanced. Not even worth the £3.75 I payed for it. Want my money back.
