Well, I don't think BOMB is really a cheating element, because it's kinda easy to make it fly away, and with SHLD and a line of METL with constant SPRK you can make things last for more time without being destroyed, like in my bunkers. Otherwise, THDR, AMTR, SING and ANY kind of CLNE are 'cheating elements'.
And thank you guys who help me, and please don't post more saves with bombs, nukes and/or weird things, destroying my bunker. It doesn't help at all.
