patlabor? Gundam? I thought it was the Prototype from Halo legends

looks very haloish

once upon a time, these great designs were the back bones of the federation... and then wtf happened and halo ends up being the only one to remember them.

now days its sparkles and naked combat, i have no clue what happened.

Yeah, Spartan Mjolnir armor must have taken some inspiration from Guncannon and friends... people today want to see drab green realistic warfare... I'll never get it.
