Gamma gun (Fallout 4)



The gamma gun is a weapon in Fallout 4.

Characteristics
Even in their most basic form, gamma guns boast considerable radiation damage. Of course, this rare feature means most gamma guns have little effect on robots, ghouls, super mutants, and the majority of wild creatures that plague the Commonwealth. However, most human enemies have limited radiation resistance. Even the most robust humans can often be defeated with several blasts from a properly modified gamma gun.

The biggest strength of the gun itself is that it consistently staggers humans and secondly, it's projectile has a relatively wide radius.

The gamma gun launches a small blast of radiation damage that explodes on impact. Upon a direct hit, the target takes a significant dose of radiation poisoning (100, or a 10% loss in maximum health).

The gamma gun also does a significant explosive damage component, which can be boosted by Demolition Expert. In fact, depending on game difficulty and enemy health/resistances, a direct hit may mean the gamma gun will do more damage from its explosion damage than from its radiation poisoning, despite being a radiation weapon.

The radiation-immunity-penetrating damage also means that the gamma gun will still do damage against radiation-immune enemies; due to how radiation works in Fallout 4, it will even do more damage against radiation-immune enemies than radiation resistant.

Due to the potentially high amount of radiation poisoning the gamma gun can do (upwards of 400 rads with a combination of Nuclear Physicist, mods, and irradiated legendary prefix), this gun can be highly effective against tough enemies, even with radiation resistance.

With the Electric signal carrier antennae, the damage of the Gamma gun changes dramatically; it still does radiation poisoning on a direct hit, but now does a higher amount of a wider variety of damage and can be charged to do further energy damage. This essentially means that while the gun is still very effective against enemies with high health or relatively low radiation resistance, it also now does a significant amount of base damage to be useful in other cases.

Variants

 * Lorenzo's Artifact - unique variant (actually a standard gamma gun with a unique Lorenzo's Artifact weapon mod); deals 25 points explosion and 10 points radiation damage per hit and can cause significant knockback on human targets.
 * Zeta gun - Similar to Lorenzo's Artifact, the Zeta gun is a standard gamma gun with a unique "Zeta Wave Barrel" weapon mod. It fires a smaller red projectile, causes 10 points of radiation damage, and can cause knockback.

Locations
Owned by Child of Atom cultists.
 * Decayed reactor site
 * Dartmouth Professional building
 * Kingsport Lighthouse

The zeta gun can be found on a table in the science lab of the cabot house.

Bugs
Due to a possible bug related to Fallout 4 area of effect damage, the secondary damage on a Gamma gun without the Electric signal carrier antennae mod is applied twice on a direct hit.
