This was featured heavily in preview material and trailers and I can't seem to find it anywhere in the game. It appears the buzzsaw is a variation of the weapon but you have to advance pretty far in the game to even be able to purchase that. Pretty disappointing to me if that's the case, but not a big deal by any means. The way of acquiring the Buzzsaw is to do all of the belltowers which requires going into Northern Kyrat, does anyone know how far you have to be in the story to access the Northern Kyrat area? Thanks for any help and clarification.
