Here's 25 arena maps made with my random map generator from the 72 hour jam. They should be functional and balanced, but I don't really have a good way to test them, so I'm putting them up for download instead.
If you want screenshots, go to the link above. There's quite a few pictures of the maps there.
Enjoy the chaos, I guess. If you run into any issues, please let me know. If anyone runs these on a server, let me know; I want to join in!
