BB Captains server · picked teams

Captains pick the teams

Sign up with the minimum number of players you want to play with; volunteer as a captain if you like. When enough are in, the game is called.

4 captains when at least 4 volunteer and 12 or more players are in, 3 when at least 3 volunteer and 9 or more are in, otherwise 2.

Up to 4 captain volunteers (a 5th is refused); a game needs at least 2. With more than 2 in the called game, its players vote on the Captains server how many captains play (2 minimum) and may kick candidates out of the captain list (half of the players there).

🎯 Tips for new players

  • Rush nades, flamers, or lasers — all viable survival paths (land mines are nerfed to −90 % on BB: don't bother).
  • Type askbot help in-game for stats and trading commands.
  • Your ELO is tracked when you play — but it's just for fun.
