Concept Design created for Oceanic. My client was kind enough to let me also share a time-lapse of designing it with Fusion 360 on Gumroad - you can get it here:
Details about Oceanic here:

I will go over the design of the weapon, my basic process from concept-blockout- to finished model.
About the weapon: This weapon is a two barreled railgun, with a 6 x2 round capacity, used for penetrating the toughest targets. The barrel has actuated coolant release after each shot, which pop up and vent heat. The weapon is self loading but is equipped with a charging handle to the rear. The weapon's sight had 3 different visual modes as well as variable zoom.
More details about the project coming soon!
