Gatling Laser (Fallout 3)

The Gatling Laser, in Fallout 3, is the most advanced weapon type for the Big Guns skill. Among other places, they are found on Enclave, Outcasts and Brotherhood soldiers.

Fawkes, the NPC Super Mutant companion, uses a Gatling Laser during and following his second meeting with the Vault Dweller. You are not able to take Fawkes' gatling laser, should you put a bullet in his overgrown head.
