Battle for the Electrolyzer was a Galactic Gladiators challenge. In this challenge, a contestant would have to survive 6 waves of enemies in order to win a brand new Electrolyzer, which then allowed the hacking of special locks. No bolts were awarded upon first completing this challenge, although upon a second completion the reward was 1,500 bolts.
