The one thing that i always felt was missing from RWRA2, was the robots live arena. I know that they couldn't include it because of legal issues, but i I decided that i would have a crack at making my own version of it anyway, and this is the result:

Bear in mind that this is the FIRST arena i've made, so it has a few issues(some areas are badly textured, no floor flipper etc).
However there is a functioning pit release button. although the pit doesn't eliminate bots when they fall in, to give them a chance to get back out again.
Hope you enjoy!
