After more than 50 attempts, I finally managed to beat First World Bank on multiplayer overkill by myself and my partners in crime. Multiplayer is slightly more difficult than single player (25 vs 20 cops), but the number of cops wasn't the problem here.
Timing needs to be perfect, facing more than one cop at a time will make you lose health, you need to pay attention to what the bots do, correct for them and be a bit lucky with the random events. Also I have never experienced as many glitches as I did when attempting this, mostly on my best runs as well.
