When I first saw this model I thought it would be great for a heavy weapon guy because the proportions make it look like it's hunched forwards and the extended intake on the top looks like its made for compensating for increased energy consumption, so that's why I did this conversion, even after so long.
I guess it would be a siege tartaros with plasma blaster in 3.0 or an armistos with some oddly large artificer armor otherwise.
It looks cool.
