NOTE! YOU CANNOT PLAY EVERY STAGE WITHOUT UNZIPPING THIS!! Highly recomended you press F1 in the game. This is a Call of Duty 4 like engine, where you play a series of matches in 3 different modes. You set the settings for the match and then start the killing. You use the mouse to look around, and ASDW or arrow keys to move. You left click to shoot, and right click to throw a grenade. The mouse aiming does not work perfectly, and can take some time to get used to. Hartless gaming helped think of the title 🙄 Enjoy!
