From the article:
It beings with a shudder. You feel it, the earth trembling around you soon, it's no longer a vibration, but a distinct pattern of three... four... no, six beats, each pounding the ground. Then you hear it. The thuds of impact, drowning out the cracking of tree trunks, the screams of wildlife as the animals flee, and then finally it bursts through the forest, one metric bajillion tonnes of steel and clacking claws, and a couple of bonus torpedo tubes.
Time to change your pants, it's the Ghordson Earthbreaker!!!
