Gun Turrent - Remember the old arcade game Tank Commander? The one where you looked through the viewer? Okay... imagine the screen of your android device as being a targeting system; cross hairs, HUD rader, enemy counter (until next level), health meter. Utilizing GPS programming and the whole motion sensing feature, YOU hold the device before you, and YOU must turn in order to turn what the display shows. Umm, let me rephrase that. Pretend you are holding an actual old fashioned machine gun, with two handles... you have to pivot in order to turn the gun, right? Instead of the gun handles, you are holding the sides of the andriod device. In order to shoot, get this, you jerk the device back ward and forward, almost as if there was a recoil from the gun itself. Early levels would just have ground based enemy units, so that the user can get used to the controls, but eventually you would then face air vehicles. Imagine it, a person turning left and right (maybe a full 360 degrees), arms jerking as he fires... the sounds of helicopters approaching, he turns and looks up, panning left and right...
Wack-a-Contact - Just like wack-a-mole, but instead of moles, you wack the images of the people you have taken photographs of. Uses face recognition software, it will wrap a face around a pre-made shape. When those faces pop up from the ground, you poke them with your finger.
