The holorifle is a scoped, pump-action energy based weapon. The weapon's main body is similar in appearance to that of a grenade launcher. The scope of the weapon also appears similar to that of a laser rifle scope, but with the advantage that the holorifle's scope features integrated night vision. However, the magnification level of the holorifle scope is only 2.86x, compared to the 3.5x magnification of the laser rifle scope. The weapon is unique in that its projectile is not a bullet, plasma, laser, flame, electromagnetic pulse, or electrical charge. Since the holorifle is based on hologram technology, it fires a solid light-based energy projectile, and so is most similar to particle-based energy weapons (i.e., lasers). On impact, the projectile applies a "holorifle damage" effect, dealing an additional 15 damage over three seconds (similar to the "flame damage" done by a flamer or incinerator) and knocking the target back. As with most other energy weapons, the holorifle's projectile will ignite any gas traps and other flammable hazards that it comes in contact with. The holorifle uses microfusion cells for ammunition, loading up to four cells in a tubular under-barrel magazine. As the magazine is internal, the weapon must be reloaded by hand, one cell at a time, resulting in longer reload times compared to other energy weapons. However, the reloading process can be interrupted for immediate firing. The holorifle thus has the singular advantage of being able to immediately fire again if less than a full magazine is needed. Due to the unique nature of the holorifle, it cannot be repaired by any other weapon, even with the Jury Rigging perk, this is because there are no other pump action energy weapons like the holorifle available. It can be repaired only by weapon repair kits, merchants, or through ED-E with at least one rank of the Camarader-E perk.
