Exercise in Perversity
A small, dark, seriously 5D map. I'm not kidding... the whole thing is repeated several times. Don't play this unless you're good at spinning around... folks will come from behind pillars on a regular basis. Carnage rates will be horrendously high, even with the invincibilities... there are fusion pistols everywhere.
