I need a Flash CS3 AS3 Box2D physics engine tank game prototype. No artwork is needed just use simple shapes and movieclips. It is not a complete game just a demo, no score, title screen, menu etc. Code should be well commented so another person can know whats going on. Please look at the attached image for further details and instructions. You must show me something you've created with Box2D on your own company website to prove you are experienced.
