I was making a DOOM build a few days ago and firing twice with the 'Super Shotgun' felt really weird, so I decided to make this.
YOU ARE HUGE! This mod makes your Mosconi shoot two shells at once, just like in Doom!
EDIT: Fire rate has been halved (500 > 250) due to request from the moderation, so the DPS remains the same as the unmodded Mosconi during Swan Song.
