Four: The Space Fight is a carefully crafter space shooter with a nice unique atmosphere, and a different approach to the genre. Chase, shoot, and destroy enemies on your iPad in a 2D Asteroids style game. In fact it's more like a fast paced demolition derby set in space. Divided into two different experiences it offers both single- and multi-player fun for hours. The game is already available for download on the App Store for iPad, but I'm heavily working on adding more content and functionality.
This video shows the 4 player face-to-face mode. It's somewhat deprecated, because the default control layout has been changed to the touch joystick version, but gives an idea of the game nevertheless!
