@Tig: I found a great map. The name is CHAMPION, it's on:gamebanana.com/mods/144391
1 opponent, 1vs1: makes super fun !
At LVLWorld CHAMPION is still missing. I do not know myself legally, whether the may be simply copied on LVLWORLD !
The author is: Scorn/or/Unknown (real name : Samuel De Cruz).
Maybe you can get the permission for LVL ?
