Everybody is a floppy rag doll. Knock them out (empty their health bar with punches, headbutts, slams and hard falls) or hold them down on the mat for 10 seconds - or throw them out of the ring: lift them with Shift near the ropes, face the way you want them to go, and right click to send them over the top rope. Tired and battered fighters wobble more and fall more easily.
On the rooftop there are no ropes and no mat to pin anybody on: the edge is a long drop to the street. Knock them out, or throw them off the building (lift them with Shift near the edge, face it, and right click). On the boat it is the same, but the deck is only a few metres above the sea: throw them overboard. Choose Random for a different arena every match.
Moves
Early test build - three places to fight so far: the ring, a city rooftop, and the deck of a boat.
Needs a keyboard and mouse (or a gamepad): there are no touch controls yet.
