This is a Siege tank from Starcraft 2, using the design for Heroes of the storm. its drawn in the style by the guys of Carbot animations, this was a patreon thing, they do several series for the blizzard games from WOW to as you probably guessed SC and SC2 go give them a look on youtube https://www.youtube.com/channel/UC1.....VmylfPVBLBvitQ its not only Hilarious but it uses some pro level mechanics in there animations that just make sense. so go check em out.

they are also working on a 2D mod for SC2 that will completely redesign Sc2 to this style, blizzard even loves their work. so go watch what they have as by this posting season 3, if im not mistaken, was just finished
