As part of the Advanced Games Studies module I spent 6 week working on a game called Armageddon my horse designed by Alex Saye. In the game you play as war, a horseman of the apocalypse and fight all the other horsemen and their armies. The game was built around a kinect extension called kinect wheels built to allow wheel chair users to use the kinect.
I mainly created the AI and most of the game mechanics, a full list and explanation of the tasks I completed see the advanced game studies blog.
