Two Barrel Shotgun

The Two Barrel Shotgun is a weapon appeared in ObsCure and Final Exam.

Location
This weapon can be found after entering the gardens from the metal gate in the west yard.

One will find a small shack and after a little walk, the camara shot will show you the shotgun in the roof. You must use a weapon to make the shotgun fall. But if you do so, an Evolved Infected and a Crab will spot and attack you.

Features
The enhanced version of the Old Shotgun, uses the same shells in a magazine with a maximum capacity of 2 bullets. The focus range is short and it needs to be reloaded after every shot (it shoots both shells) but each shot does 40% more damage than the regular shotgun, making it the second most powerful weapon in the game, the first being the grenade (and not counting the laser, since its damage is calculated differently, instead working as a very powerful flashlight).

Through the use of adhesive tape it is possible to combine it with different types of flashlight.

Final Exam
In Final Exam, this shotgun can be obtained in Leafmore High in chapter "Underground Investigation". It can only hold 2 bullets, with a maximum of 16 bullets, it's the firearm that can carry more bullets in proportion: 8 shippers. Reload times are long but it's compensated by its high firepower and you can shoot very quickly.

Trivia

 * Even though it's a Two Barrel shotgun, when a character reloads it they will "pump" it, this was probably kept this way so the developers didn't have to make another animation.
