the gun pointed at the head of the universe
it's alright once you get used to it; the first time it comes up you groan a bit, then, providing you have competent teammates you relax and get into the flow of it. the second time you're 'warmed up' so to speak, and get into it a bit.
the third and fourth time your soul begins to be sucked from your chest and you just sit there hollow eyed like an automaton.
it's like playing uncaged four times in a row outside of rumble pit. even your thoughts become grey and sound like jetpacks.
