Grenade Launcher (Doom 2016)

Grenade Launcher is a multiplayer-only weapon introduced in the Bloodfall DLC.

It's a revolving Semi-Automatic Launcher that lobs Grenades, similar to those appearing in the Quake series. Its weapon modification detonates a smoke grenade.

Trivia

 * A Grenade Launcher also appeared in Skulltag, a multiplayer mod/sourceport for Doom II and the Doom website even references this by describing it as being banned like the skulltag description.
 * The assets used for the model appear to have been taken from the cut Assault Rifle and Nailgun models in the DOOM beta files.
