Yeah, the last man standing ends game setting may work better with FFA, but seems to have problems with teams. Maybe because it doesn’t have customisability.
It must have been changed at some stage to not start Last Man Standing until there are 2 or more people, last time I looked into it, it would end the game for one player, making solo testing impossible.
I’m gonna point you to a post with device setups for a team based last man standing, Its a bit full on, so feel free to post here or message me until you get it working
