i make life (and the server) rue the day it thought it could give me Cave. it's a different, yet enjoyable boss to play as, between the lemons dealing fire damage which can easily be nulled if medics, pyros, and engies are alive, but so far i've been able to (every now and then) render them out of the equation by the time my inner douche kicks in at 2 people left.
but half the time i lose. not that i mind.
