Episode 2

Dara O Briain, Angela Scanlon and commentator Jonathan Pearce oversee the ultimate robot fighting competition.

In the second heat of the series, returning champions Carbide mount their title defence against some of the toughest machines in the competition. They have to fight through brutal group battles and nightmarish knockout rounds in order to make it to the heat final. Robots in this heat include runners-up from last series Eruption, fellow grand finalists Aftershock, Crackers N Smash, champions Carbide, Gabriel 2 and Big Nipper. Along the way they must dodge arena hazards, menacing house robots and the all-new Fog of War. But that's not all - this series there is a playoff battle for third place, culminating with the second- and third-place robots battling it out in a massive Ten Robot Rumble for a wildcard spot in the grand final.

Let battle commence!
