I've done this, I wouldn't exactly call it cheating, in Bank Heist if you go out of the map the alarms go off, and in Election day if you fall into the water you freeze, and you can't win. On day 2 of election day you can also fall out of the map, and unless you die, you also can't escape. If you want me to whip it up for you, PM me. It's useful for certain things like cook off, how the ammo past those invisible walls is unattainable, although some weird things have happened while using it. I haven't tried it on Go Bank but I'd imagine it would be pretty useful.
