(SpartanTeen is commenting on the model, while the SpartanNerd is taking pictures.)
Heavy arms whole body is a weapon.
Lots of details need paint, so the details will pop.
I messed up at first, and decided to trick it out with battle damage.
Painting the joints makes them easy to come apart at the chest doors for the Vulcan cannons.
The hands are a pain. The interchangeable hands make it easy for Heavyarms to drop his gun.
Why didn’t the beam saber come with a blade?
The chain ammunition comes apart easily, and the bullets go everywhere.
It is very sturdy, and probably could survive three foot falls.
This is my favorite model so far.
