Pretty early on after Left 4 Dead was released, my friends and I, playing the zombies in online multiplayer, discovered an insidious form of attrition warfare. We found that it was possible to push a box in front of an elevator door before the humans could fully ascend to exit it.
So the elevator door would open, and then the humans... just couldn't leave. Their confusion at the obstacle was palpable. We took to watching them for a few moments out of sheer schadenfreude. Then we proceeded to terrorfuck those humans to death, securing their defeat. This went on for days in various matches until Valve patched the box from being a dynamic rigid body to a static one, or at least one with such high mass that we were unable to apply enough force to move it anymore.
