THIS VEHICLE IS NOT COMPLETELY VALID ANYMORE. Yes, you can still make it, but you'll have to drop down to T1 SMGs and no rectifier of course.
This robot was made out of boredom one day and designed to look kind of like an Indy 500 car or a Hot Wheels car. What makes this thing actually functional in a battle is the Tier 3 SMGs I have on it, which can bring even a tank with 15 Tier 1 SMGs on it to it's knees. Great fun!
