A few days ago I had an idea to build a small arena where there would be two teams of two and they would get to design their own bots and choose their weapon for them and do other things to modify them and stuff. The teams are chosen randomly by the admin from the audience. So I got to work and today I finally finished it. Here are some pictures...
The overall view.

Team 2 platform

Team 1 platform

Note: Team 1 has the two buttons, just in the screenshots you can't see them.
The red button releases your zombie and the white button lets you view the fight. When your bot is released it will wander and when the two bots get in range they will fight to the death.
Here is the door that you walk into and it comes up to the stage.

There is also an admin control box.

So that's it. Remember this was just supposed to be a small little thing that I built out of fun. You may rate x/10. Constructive criticism please.
