The new cannon system will be coming soon- featuring multiple barrel firing pieces, ammo clips, customisation of shell modules, realistic mantlets and rail gun components.
Ammunition is customised separately from the guns and transferred into the ammo clips through piping. The ammo clips and autoloaders feed the ammunition into the multi barrel firing pieces.
The next teaser will show you how to create HESH, HEAT, SABOT, fragmentation and flack warheads, as well as many others!
