BigBoom and headOfHorrors:
When you have godmode enabled (or not) and a bunch of baddies (zombies, werewolves, brides, whatever) attack you at once and it seems like you can't do anything but get caught and chomped then press F10 and type - bigboom. It has an inconsistent effect, sometimes it kills only one (which means you have to do it again to get the others) other times it kills anyone immediately around you. You may have to first have the headOfHorrors cheat enabled for this to work correctly.
