>>5608883>JEZZAIL QUIDDITCHThe historical setting could be one route also, use Afghan or Indian jezzails with long stocks and barrels, they look a bit like Harry Potter broomsticks hehe. But I think you would run out of gun ideas after a while, there are only so many variants of matchlock and arquebus etc.
I just like the idea of playing as the DEATH EATERS, just like how the Helghast were always cooler than ISA in Killzone, it would be tantalising to play as Tom Clancy tactical Death Eaters vs muggle apocalypse collapse
