- — Craig Charles introduces Robotic Soccer in Series 3, Heat B
Robotic Soccer was a small side competition held throughout Robot Wars: The Third Wars, based on the Football Trial from the First and Second Wars. Eight competing robots - most of which did not appear in the main series - were divided into four two-way qualifiers, where they were required to score a single goal in order to secure a place in the final round. In the final, the first of the four finalists to score a goal would be declared the overall winner. In the event that no competitor scored, the last robot to remain mobile, or the robot which was considered the most active player by the Judges, would be declared victorious.
Other robots, including Razer and Miss Struts, were due to compete, but their matches were cancelled after a behind-the-scenes accident. The latter robots instead entered - and won - the Pinball Competition and one of the Walker Battles, respectively.
|Robots competing||Image||Heat featured||Runthrough||Winner|
|Velocirippa vs Demolition Demon 2||Heat B||This was a quick match, with the faster Velocirippa driving around and pushing the ball into Matilda. Matilda then nudged the ball about briefly, and pushed it sideways near the slow Demolition Demon, but Velocirippa zoomed in and scored pass Dead Metal who moved the wrong way in an attempt to save.||Velocirippa|
|Malfunktion vs Gnasher||Heat E||Both robots steered slowly to the ball, and Malfunktion attacked Matilda with its angle grinder. This distraction allowed Gnasher to collect the ball and made an attempt on goal, only for Matilda to interfere, and Dead Metal to block the ball. However, Dead Metal retreated and made no attempt to block Gnasher's second attempt, which went in.||Gnasher|
|Evil Weevil vs Alien||Heat E||Evil Weevil got the early possession of the ball, and pushed it to the back of the arena. Matilda went for the ball while Evil Weevil speared Alien. Alien took the recovered ball back to the back of the arena, where it got stuck on the side wall. The spike on the arena floor flipped Alien, but Dead Metal intervened and pushed it the correct way up, but the latter had stopped moving. Evil Weevil collected the ball but it bounced away. Evil Weevil then reversed into the ball on-target for the goal, and it bounced off Matilda's eye. It went to a Judges' decision, who ruled in favour of Evil Weevil.||Evil Weevil|
|Spectre vs The General||Heat J||The General was the first to the ball in this match and bulldozed Matilda from behind who pushed the ball back afield. Spectre then attacked The General to grab possession for the ball but it escaped. The General dribbled the ball towards the goal. It bounced off Matilda and Dead Metal couldn't prevent it from going into the net, giving The General the win.||The General|
Velocirippa vs Gnasher vs Evil Weevil vs The GeneralEdit
Velocirippa drove in first, but missed the ball. Gnasher slowly moved the ball goal-bound before Matilda attacked it, while Velocirippa then suddenly broke down. Matilda accidentally passed the ball to Evil Weevil while blocking Gnasher from it. Evil Weevil tried pushing the ball down field, only for it to be bounced into the air by Matilda's block. The General then had its turn with the ball, but didn't move it far as it then attacked Matilda and gave the ball to Gnasher, who was then tackled by Matilda once again. Meanwhile, Evil Weevil then disposed of Gnasher, by flipping it onto its back by the flame pit, using its lifting forks. Matilda pushed the ball into the arena side wall, which gave it back to Evil Weevil again. The General appeared to then grind to a halt, and Sergeant Bash used its flamethrower to set the ball on fire.

The General and Velocirippa then all of a sudden came back to life, Evil Weevil gingerly rolled the flaming ball away, but the match ended in a Judges' decision, as time had run out. The judges voted in favour of Evil Weevil, mainly for its immobilising attack on Gnasher, and being the most functional robot by the end.
