This is a study I did of the second Kargan Mekton, the Rampage. I came up with an original shield for it, which I've used a standard accessory for a lot of Kargan mecha. I might do more with this down the line.

Oh yeah: Mekton, Karga, and the IMK-05 Rampage are property of R. Talsorian Games. No infringement intended nor implied.
