Change models just by switching between Male1, 2, 3....
Enable bot balance for team DM by configureing individual bots, 1st bot blue, 2nd red, 3rd blue, ect... and randon order set to false.
Not sure how to do this in multiplayer.
If the teams are 2v2 only bots (min of 4 players) and 4 ppl join one team, well all the bots leave and stick everyone SOL
