Rocket's Red Glare

Rocket's Red Glare is an achievement/trophy for the Fallout: New Vegas add-on, Lonesome Road. To obtain this achievement/trophy, you must buy (not install) all the mods for the Red Glare.

Obtaining the achievement
This achievement may be earned at the very beginning of the expansion, after ED-E opens the first commissary. Simply purchase the three upgrades, as they don't even need to be installed on the gun to earn the achievement. You need at least 30,000 caps to do this though so it is considered very expensive.

Otherwise, you can find the modifications very rarely around the Divide.
