|This archaic laser has been studied for centuries. Gungeonologists can only conclude that it was used by primitive people to poison each other with radiation.|
Gamma Ray is a gun that fires a continuous green laser that slightly curves towards enemies and has a chance to poison enemies.
- Beta Ray - If the player also has Irradiated Lead, Gamma Ray's beam grows larger and deals more damage, but no longer travels instantaneously.
- Gungeonite - If the player also has Clear Guon Stone, Gamma Ray will leave a trail of poison.
- Meltdown - If the player also has Big Boy, Gamma Ray branches twice to form a spread of 5 beams and using Big Boy refills 100 ammo on the Gamma Ray. Ammo restoration only works if Gamma Ray is held when activating Big Boy.
- Gamma Ray can put out the fireplace in the Keep of the Lead Lord.
- Prior to the Supply Drop Update, Gamma Ray did not curve towards enemies.
- Mean Green is a probable reference to The Hulk, who was transformed into its form by exposure to gamma radiation.
- The Beta Ray synergy is likely named for Beta Ray Bill, another Marvel Comics character. Alternatively, it may be a reference to beta decay particles.
- The Gamma Ray bears some resemblance to the Laser Pistol from the Fallout series, specifically the AEP7 model that appears in Fallout 3 and Fallout: New Vegas.
- If the Beta Ray synergy with Irradiated lead is obtained, it changes to look like the AER9 Laser Rifle from the same games.
- Fallout: New Vegas featured a special iteration of the Laser Rifle, the AER14 prototype, that, coincidentally, fired green lasers instead of the usual red.
