The Nuka-grenade is a powerful improvised explosive device. It incorporates the radioactive properties of a relatively rare Nuka-Colavariant to produce an enhanced plasma blast. On detonation, the 21-foot blast radius is bathed in blue-white flames, while an interior 9-foot circle is doused in extremely high levels of radiation, to the tune of 50 rads per second. The radiation dissipates fairly quickly.
Note: this item is also craftable via a dialogue option with Veronica, or with ED-E (with at least 1 rank of the Camarader-E perk).
This weapon must be crafted by the player. It cannot be found on enemies or in containers.
There are very few bottles of Nuka-Cola Quartz in the game (22 in the base game). The Nuka Chemist perk allows the player to create more. More Nuka-Cola Quartz can be found in the Old World Blues and Lonesome Road add-ons.
PCPlayStation 3Xbox 360 Nuka-grenades are only classified as a standard holdout weapon: they are not added to the list of advanced holdout weapons, so if you have a Sneak skill over 50, you will not be able to bring the weapon into holdout areas. This same bug also affects the tin grenade, MFC grenade, and Li'l Devil.
