UNSC Mammoth

The M510 Mammoth siegework has no equal in size, firepower, or tactical faculty within the UNSC's mobile planetside support contingent, making it one of the most powerful ground assets ever designed by humans. At roughly 70 meters in length and carrying numerous mounted support weapons and materiel caches, the M510's most significant attribute is its topside MAC, designed to target and eliminate hostile vessels, weapons, and even fortifications residing in terrestrial or even suborbital positions.

Ideal for kids ages 8 and up!

    This is the most impressive set I have seen from Mega Blocks, and I am hoping they will go on to make sets like it. I like ho it is compattible with the night ops Gausshog. I just with the Gausshog cam with it :).

    The mammoth is awesome for playing. Also I would advise buying the night ops gauss hog because it goes well with the set and the mammoth is very cheap for what it could be.

    Fantastic model. Love it. Only problems I'd have with it was that it was missing 3 parts: the Roland A.I. hologram piece, the hologram stand, and a piece for the mini-MAC cannon. But since mega bloks ships you free spare parts, it's hardly a big deal. Also, this model is VERY time-consuming. I'm no stranger to labor-intensive model builds, but this one still took me 12 hours straight to build, so keep that in mind if you're buying this for a child. All that being said, this is still a great, fun model for any Halo/Mega Bloks enthusiast (assuming they'd have the patience for it). If you can afford the price tag, definitely go for it.
