While levelling this up, I was cloaked on the elevator shaft roof on Skyline, I jumped for an Air Stomp towards the left (as you face the helipad) when I saw one guy, and then mid-air spotted a second sheilded by the wall. Double Kill I though to myself! Nice!
Landed, achievement pops up. "The Cleaner". WHAT!? Surely not!? Ticker updates, kill, kill, kill, kill, kill - PSYCHO!
Freak luck against a silly team, but massively happy regardless. I previously thought there was no way anyone could get a Psycho in a 6 man game legit apart from dumb luck, and I got the absolute dumbest luck possible!
I can now retire, and will never hear a bad word against Air Stomp ever again! But god damn if I don't now wish this game had a theatre mode!!!
