Battle-Siege is a minecraft mini-game. The game starts with two unequal teams (in previous games there were two versus six and three versus seven battles). The team with less members does not have a disadvantage. It's the other way around, in fact. The team with less members has 15-20 minutes in creative mode. They use that time to create a base to defend from the other team. After that time is up, they switch back into survival. For the team with more members to win, they will have to eliminate the other team entirely. There is a block of obsidian that also has to be protected by the team with less members. If it is broken, that team will lose. NoochM is normally on the team with less members, as he is a master of TNT.
