i think that the Kraken's "meat fueled" ability is inhierent to the model. i think that its guns are going to be on the SuperStructure. they do not look like they have arcs like its arms.
i also highly doubt that our collossal is going to be ARM 20. i think that it will be ARM 19.
D3+1 shots on its minigun sounds likely, i'm already thinking of the possibilities of a Cryxian gun-line army.
i can't wait to try this thing!
