Just a bug which I noticed on Aloha Last team standing.
Basically, you can leave the spawn boxes (those rooms which have red walls surrounding you and which fall down when the round begins) before everyone else by pressing two keys.
I'm not going to post here what keys let you do this, simply because a lot of people would then abuse the bug. :P
Who's the guy who made the arena script?
I want to PM him about this bug. ;)
