'Killbot' is a song made by Devin Martin. It was first heard in the teaser trailer for Madness: Project Nexus. A remix of Killbot is heard at the end of Mission 1-G, when you fight a G03LM Mk2. A slightly sped-up version of the remix is also heard during the final fight with Mag Agent: N.
Krinkels has made two drawings of dubstep robots based off of the song Killbot. The original was a robot with subwoofers on its arms, whilst the second was 'more of a DJ model' and could spin turntables with its hands.
