Two teams, each with two robots, entered the arena at once. Only one member from each team was allowed to battle at any one time. If a robot wished to let its team-mate into the action, it was to return to its CPZ. There, the robots could switch out and tag. However, these rules were very frequently broken and battles often featured all four robots battling at once. The tournament featured four teams; two American and two British. The first two battles were qualifiers to decide which team would go through to the final to represent their respective country. There was also a playoff for third place between the heats and final.
