The Enigma was a tracked robot which F2Q for series 3. It had a similar design to Vlad The Impaler (the very successful Battlebots competitor) but only tracked. It was armored in aluminum and had lifting forks as the weapon. It intended to enter series 4 slightly renamed as Enigma and a modified design but it was never completed.
