This facility is for post-based fights through organized challenges and/or just random madness.
However, there are "rules", if you can even call them that:
1. God-modding.
Use discretion; we're actually allowing you to do whatever you want, but that doesn't mean your opponent won't just grab his ball and go home if you start making his head explode by snapping your fingers. G-mod responsibly.
2. Follow ground rules for each fight
This can be tied into combatants agreeing/disagreeing to God-modding; whatever ground rules are set, they are to be followed for the rest of the match (i.e. Swords only, sniper battle, etc.). Fight honorably.
3. No interrupting fights like a *****
Anyone is allowed to spectate and "cheer from the stands", but interfering with matches that you are not directly given permission to be a part of will most definitely be ignored or met with "*shoots _____ in the **** head*". You do do whatever, but try to only jump in if you feel you can contribute something worthwhile to the fight.
Battles can take place whereever you want them to; the arena "transforms" into various any place you can think of; it's comparable to the Holodeck in Star Trek, yet also similar to the Danger Room in X-Men (hell, you can fight there if you want too). The surroundings can be just as freely utilized as any of your weapons.
Other than that, there's not much else except to fight and maim one another. Have fun!
