Resident Evil 3 · Weapon upgrade
M3 Shotgun: Shell holder
The Shell holder is an M3 Shotgun upgrade placed along the Underground Storage fuse-maze route, behind a hydraulic lift.
How it works
The source places this part within the Underground Storage fuse maze, in an area behind one of the hydraulic lifts. It identifies the Shell holder as an M3 Shotgun upgrade but does not state its effect, whether it changes capacity, or any further collection condition.
