The map is a 1v1 to 3v3 "fast-paced" elimination gamemode across 9 tiny format maps, with 18 weapons and 32 modifiers that get randomly picked each round (You can disable some in the lobby). You can keep it competitive or just let it get completely chaotic with friends. The gameplay loop is pretty good.
Would mean a lot to get some feedback from people who try it out.
