Team battles run on @marswolfbot. Add it to your group next to the game bot. The game bots redirect to it when someone tries to start a battle.
Random battle
/startrandom splits everyone at random into equal teams of 4 to 13 players. If the players cannot be split that way (11 or 17 players, for example), the game waits a little for more players, then the last to join sit the game out. Every team gets the same roles.
Organised battle
/startorganized with comma-separated team names, for example /startorganized 🐺,🦊. Each player joins the team whose name is in their first or last name. All teams need the same number of players, 4 to 35 each, and every team gets the same roles.
Chaos battle
/startteamchaos splits everyone at random like a random battle, but each team draws its own random roles.
Winning
The last team with players alive wins.
