Well Voidy.
Heres how it went back on the old Chronic server. People entered in !solo, which would enable 1v1 mode of sorts, whoever enabled that command would be slain at the beginning of the round and whoever didn't kept playing in a group. Once the group who didn't enable !solo dies, a random person who enabled !solo first would be up against the bot by himself, after that person dies, another person who enabled !solo would be up next, it would iterate through all the people who did !solo until everyone died, then the round would end.
That enough of a description? :3
