Old Faithful is a unique weapon in Fallout 4.

Background

The following section is transcluded from Laser pistol. To modify, please edit the source page.

The standard energy sidearm of the United States Armed Forces, the AEP7 replaced the AEP5 model. Boasting redesigned internal components, including a new photonic focusing chamber and completely redesigned focusing crystal pattern, the AEP7 offers a respectable damage output, excellent accuracy at range, and generous battery size. By taking advantage of new manufacturing techniques developed shortly before the Great War, it also boasted reduced weight and bulk compared to previous models.

It's entirely likely that if wartime logistic troubles did not delay development and deployment, the AEP7 and its superior version, the AEP9, would have entirely superseded the N99 10mm pistol as the standard sidearm of the U.S. military. As it stands, the Great War prevented it from being widely deployed, despite a large number of units being produced. Repair and calibration are generally recommended whenever a functional laser pistol is found.

Characteristics

Old Faithful is a unique laser pistol bearing the Instigating prefix, allowing it to do double damage to targets that are at full health initially. At high levels, Old Faithful can spawn as a laser rifle instead.
