Today Lizard Dude and I played four straight campaigns of Left 4 Dead on Xbox 360, my first time playing the game on not-PC.
On our last campaign, which was versus on No Mercy, I got the All 4 Dead achievement on the second-to-last stage, where the elevator goes up and there's half-finished walls and stuff.
I spawned as the tank right in front of a forklift, which I repeatedly fed to the survivors, three of which died instantly. The last one needed some persuading via my giant fists before I was able to down him and get the bleep bloop.
