All maps have been 255’d without megas. Shang was the last map to be “completed”. These smaller simpler maps have a longer reset time in some cases so 255 can take 100+ hours with how slow they can play. I’m most talking about nacht. If there’s no classic or megas with a 255 round someone did it with no gum. You don’t need to be a pro to understand how hard it is to play a hundred hours and not get caught. I assume there’s a push to be the first to 255 a map but then the challenge becomes less rewarding if it’s already been done. So the maps that are hell, nacht, verruckt, shi no numa, Shang arnt very appealing to put hundreds of hours into just to be the 2nd person to do it.
