Basically, speedkarts with presumably a hurtful touch from the front. You either have enclosed maps (where you're forced to drive into them) or open areas (where you can maneuver around and try and get them off the platform to their death)
it'd use the same speedkarts as the original speedkart
i was thinking that after the countdown, presumably done in chat or something, the blocks that are used to spawn your speedkart dissapear and become passable, via events.
discuss i guess
