Back To Rock III vs. Knyfe:
Could depend on Knyfes setup, but Id guess BTR.

Mega Masher 2 vs. Infusio...SOR X:
SOR X to win rather easily here.

Apocalypse vs. Drumroll SR:
Would depend who got under the other first...Drumroll possibly.

QE2 vs. Wedginator Devilution
We meet again, Mister Kody...
Avoid the front. I should be able to get around the sides; tilted wheels or not, 4WD beats 6WD. :P Once Im in around the sides, lift, clamp with the axe, and take it to whichever hazard I fancy, or possibly the Void.
Failing that, flip over and axe the underside to hell If he tries to get me on his flipper and hold me there, I shall squirm like squirming is going out of fashion, which combined with random weapon firing might jiggle me free.

Good luck Kody
