Color swatch for Vi’s cannon from our 15-second commercial spot.
I knew I wanted her to wield over-sized heavy artillery, but it was a blast finally sitting down to finalize the gun design. I know it’s just a cartoon, but I couldn’t resist getting into the detail of how the thing theoretically works.
It’s a variant from the standard-issue shock trooper rifles, which house their spring power within the cartridge. Of course, the shock troopers wouldn’t imagine a need to take out anything larger than a dreamkeeper - but the rest of us know better.
To better serve as a demon-killing weapon, these cartridges are powered by a much larger, more powerful gun-mounted spring casing. This allows the rounds themselves to be completely solid - composed of two materials, one heavier for maximized penetration, and the other a casing intended to shatter and fragment laterally upon impact, for an expanded kill-radius.
The recoil from the firing causes the gatling barrels to rotate, and partially re-compress the spring mechanism.
Normally these cannons must be affixed to a stationary mount due to weight, but Vi’s going to be power-active in the clip, and thus will be wielding it manually.
I would also like to add that animating that cannon traditionally in a 3-D rotation was hard. Just so you know.
