NOTE: This gamemode has been removed Edit
It consists in approximately 20 aleatory tier players (tier 2-7) fighting against one tier 9-10 player (the Boss) or against one tier 8-10 platoon in the arena tileset used in Practice Mode. To win the players can either kill the Boss, or capture the base at the center of the arena, waiting out the timer would result in a win for the Boss team. This mode happens in an aleatory way, so you may or may not play this mode. Winning rewards the players with a bunch of RP (2000 or more, mainly because of the high handicap bonus) and a good amount of tech-points, that allows them to get to the next tier faster than in normal battles.
Low tier players (2-7) join the fight randomly (also if they are in a Platoon).
