The Sixth Wars featured a variation on the format of the Fourth Wars. Eight robots started each heat, divided into two, four-robot melees. In each melee, two robots were eliminated. The two surviving robots were each paired against survivors from the other melee for the second fighting round. The two winners of those matches fought for the heat championship.
The 'Loser's Melee' carried over from the format in the Fifth Wars. Losers from the first round of the semifinals fought in a pair of three-robot melees with the winner of each melee re-entering the tournament tree.
