Started this piece in Zbrush as a concept and to try my hands of Hard Surface sculpting but finally decided to complete it. Model was done in Zbrush and rendered in Keyshot with some post work in Photoshop.
For the game resolution models they were retopped in Modo, Texture painted in Substance Painter and Rendered in Marmoset Toolbag.
Below are snapshot of Game Resolutions Models. Rretopped in Modo, Texture painted in Substance Painter and Rendered in Marmoset Toolbag.

Thanks Huber.
Here are some snapshots with the Cavity shader and Clay shader in Zbrush to highlight some of the details in Zbrush.
These are links to Snapshots from Zbrush they big in size so had to upload them on DropBox.
Decided to Remove the GunShot i felt it was looking little odd. Below are some new Snapshots and links for High-Res.
