The gamma gun is a ranged weapon in Fallout 76.

Characteristics[]

The gamma gun is a pistol that does ballistic, radiation, and sometimes area energy damage (with mods), with a large orb projectile (much larger than normal hit detection box). The projectile is highly visible with a similar effect to the scorchbeast sonic wave attack.

It can be modified to increase its lethality. The radiation damage component has no effect on creatures immune to radiation, such as super mutants and ghouls.

Notes[]

  • This weapon is affected by the Grounded mutation. This does not apply to the radiation damage component.
  • The explosion the projectile creates on impact deals damage when modified with the electric signal carrier antennae and is affected by Demolition Expert.
  • Fireproof has no impact on the radiation damage, despite it being dealt by the gamma projectile's explosion.[2]
  • The gamma gun is useful as a tool to maintain one's desired radiation levels.[clarification needed]
  • The gun can be useful for player-vs-player combat, especially with the Quad legendary effect, due to its projectiles being difficult to dodge and able to rapidly irradiate players.
  • Cultist prophets wield a modified gamma gun which appears to release the same sonic energy as mothmen.

Bugs[]

  • PCPC Xbox OneXbox One Playstation 4Playstation 4 When modified with the electric signal carrier antennae, only the ballistic damage scales with charge level.
  • PCPC Xbox OneXbox One Playstation 4Playstation 4 When modified with the electric signal carrier antennae, the gamma gun deals it's energy damage over an area.[3][patched]
