I had tamed this beast (cheats) and I will now share some knowledge with you. Not unlike the Megachelon and all other titans, the tek platform on its back creates a gravitational field of its own and it is the 1/2 Titans with ranged area attack, next to the desert Titan.
How to tame a titan:
Step one: piss your pants
Step two: grab a mek
Step three: shoot the glowy thingnies
Step four: piss your pants some more
Step five: destroy all of the glowing orbs until it falls down.
Step six: click tame kaiju
Boom you have a titan
