Well, I continued with da Boss and his mega armour.
Here you can see I added a cross-hairs sight, as well as I started with his Dakka arm.
Then I added a visor over the helmet, as well as a lot of extra armour to the arm, plus some details to the guns.
I'm not sure what the glyph over the barrel of the central gun means, but I'm sure the Mek had some kind of intention *snicker*
Ah, yes, ammo
Looks like plenty (well most likely just enough for one extended burst, but talk about reality in 40K)
Then I started to work on da killy claw.
Looks like he grabbed a not-so-fortunate Beeky.
