Super shotgun/Doom 3

The Double-Barreled Shotgun, also known as the Super Shotgun, is a weapon introduced to Doom 3 by the Resurrection of Evil expansion pack. It is first found in Erebus Control in Sarge's office.

Combat analysis
The Super Shotgun has nearly equivalent strengths and weaknesses as its classic Doom namesake, since it's a sort of remake of that weapon. It has the same tactical value. Extremely powerful, firing both barrels at once, the double-barreled shotgun will instantly kill most monsters at close range and severely wound more powerful monsters, but loses effectiveness at long range. Reloads rather quickly but its low ammo capacity and single shot can prove slow in a crowd of monsters.

The differences between the super shotgun and the regular one are mainly that the super shotgun (as it's nickname implies) is more effective and can cause more damage. Another significant difference is that it only holds two shells at one time (enough for one shot from the weapon). As its name implies, it uses the same kind of ammunition as the shotgun, shotgun shells. Additionally, it is far more accurate than the regular shotgun.

Tactical Analysis
The Super Shotgun can kill any enemy up to a Revenant in one shot, provided that all of the pellets connect. If aiming for the head, the Super Shotgun can kill powerful foes such as Hell Knights within three shots. When going against multiple foes or a powerful foe, use the Artifact so that you have enough time to successfully evade attacks and get close to a target without getting hit.
