I've decided, because I had nothing better to do, to take a little footage of the MKII blowing up the Nod base, or what's left of it, in the GDI White House mission.
Everything looks in order, save for one detail. It's that the Mammoth's feet seem to glide over the ground. Not all of them, but the ones that aren't taking a step don't move, yet they slide over the ground. It could be the locomotor that's the culprit, but I find it a bit unrealistic (I know a game of this type was never meant to be "realistic", but it's the one term that works best).
