found a way to play with 352 commanders..so im here to brag i got headhunter 130 =D vs brutal ai
you need custom 8 teams and auto balnace commanders on.. then make 1 ai on each team.. start with as many humans as you like on team 1.. and place the remaining 44 ai on team 8.. each team will auto balance and the result is insane..
if you dont set commanders max level 1 then ai breaks because they all try morph at same moment they excess in metal. if you can survive till nukes while they kill each-other you can get like 30 commanders per nuke
even without nukes this might still be possible because the ai has a huge war.
