The classic, legged mechs have long been obsolete, having evolved into tanks over time due to the simple fact that a walking vehicle is far to unstable to even be a threat to Don Knotts, a well known deceased Litch. These primitive walking mechs were only capable of harming opponents by falling on them. "No more!", says scientist Albert Einstein, via an Ouija board, "A new era in mecha is dawning. I only regret I will not be here to witness the carnage."
