The Nuka-grenade is a craftable thrown explosive in Fallout 3.


Nuka-grenades are crude, yet effective, bombs consisting of a sealed tin can filled with Nuka-Cola Quantum, Abraxo cleaner and turpentine, which react with one another to explode. Around the middle are several strips of masking tape and the words "RADIATION" and "DANGER" written on both sides in black marker.

When thrown, the grenade erupts into a great blue and orange fireball. Its power is bested only by the mini nuke and the bottlecap mine (with perks). Flames and radiation linger for a few seconds after the explosion.

Thrown grenades are affected by physics; they will bounce and roll based the surface(s) they come into contact with when thrown.

  • Grenades can be targeted in V.A.T.S. and can thus be shot out of the air. Shooting them while they are still held by the enemy can detonate them as well. Grenades can be thrown point-blank in V.A.T.S due to the sharply reduced damage taken.
  • An incoming grenade will show up on the HUD as a red arrow denoting its direction relative to the Lone Wanderer. Move in the opposite direction as quickly as possible to escape the blast radius.
  • Holding the fire button down for a longer period of time will increase the strength of the throw. Grenades can be thrown for longer distances than normal through successful V.A.T.S. hits. Grenades cannot be cooked to detonate earlier.
  • It is also possible to plant a live grenade on a non-player character via reverse-pickpocketing.
  • Nuka-grenades are not affected by either the Demolition Expert or the Pyromaniac perks.
  • Followers do not seem to account for the Nuka-grenade's increased explosive radius when using them, leading to frequent friendly fire.
  • Having the Quantum Chemist perk provided by the Broken Steel add-on allows turning ten regular Nuka-Colas into a single Nuka-Cola Quantum, and since regular Nuka-Colas are much more common and can be found in restocked inventories of some merchants, the perk allows creating an essentially unlimited supply of these grenades.
  • The Nuka-grenade should be used very carefully at close ranges. Besides having a risk of dealing massive damage to the user when used incorrectly (just like any other grenade), the radiation levels from a Nuka-grenade explosion can be astoundingly high. It produces a lingering radiation level of 50 rads for 2 seconds that is roughly half the size of the explosion itself.
  • In the G.E.C.K., the Nuka-grenade is called a Nuka cocktail, as its original design was based on a Molotov cocktail, using a Nuka-Cola Quantum as a component. The model for this early design can still be found in Fallout 3's projectiles folder of Meshes.bsa.
  • If one is thrown on (or at) Harold, he will catch on fire before it explodes.

Behind the scenesEdit

Originally, the Nuka-grenade was planned to be designed in a form of a bottle, resembling the Molotov cocktail.
