Forge World’s big Ork tank mounts a huge gun ready to take on any Imperial BaneBlade or even Titan. The Kill Bursta mounts a huge-bore Kannon capable of destroying bunkers and siegeworks with ease.
The last time I looked at the model I had given the model a double undercoat of white and black and then using a thinned Chaos Black I touched up the black basecoat. I also black undercoated certain parts of the engine.
The first thing I did was something different and sprayed the upper surfaces of the model with Citadel Spray Zandri Dust. Using a brush I painted the tracks with Gorthor Brown.
I painted the rear engine with Leadbelcher. I also painted the small turret weapons with Leadbelcher as well.
This covered the basecoat rather well, and the black undercut added shadow.
I also started painting some of the panels with other colours, notably Balor Brown and Ushabti Bone.
See how I constructed and undercoated the beast on the workbench feature on the Kill Bursta.
