Serious Sam 4 - Unused Grenade Launcher Attachment for Double-Barrel Shotgun
The Double-Barrel Shotgun model contains an attachment for the underslung grenade launcher as well as animations for firing and reloading it (but no mounting animation). In the final game, only the Single-Barrel Shotgun can use the underslung grenade launcher. It's not clear if the Double-Barrel Shotgun version of the grenade launcher shares the same properties as the Single-Barrel Shotgun version. This video showcases a modified underslung grenade launcher that has Double-Barrel Shotgun usage enabled.
The reloading part of the Double-Barrel Shotgun's grenade launcher fire animation cannot be cancelled before it's done playing because it lacks a "RecoilEnd" generic event in its firing animation.
