Screen cheating. Screen looking. Screen peeking. During the golden age of 90's splitscreen gaming the simple act of looking at your friends corner of the screen has been called many things, usually starting with a curse word. With the popularity of online console gaming skyrocketing last generation, screen looking had become a thing of the past... until now!
Screencheat is a local and online 4 player splitscreen FPS inspired by N64 games like Goldeneye. Players can see each others view point but with a twist: everyone is invisible. To find out where your opponent is you'll have to look at their portion of the screen. Areas are color coded so you instantly know where they are. When a weapon is used there are effects like smoke or flames that can give you a hint at where they are on your own screen too. SC has 8 unique weapons, 5 maps, and 5 game modes. You can also combine local and online multiplayer, like 2 people on the same computer and 2 randoms online.
