The Complete Fallout 4 Weapon Guide

Grenades

Grenades come in different flavors, each with their own special uses.

Molotov Cocktails- Bottles of liquid fire. Useful against most living things such as humans and animals. Robots will shake off the flames (they’re made out of steel after all).

Fragmentation Grenade- You’re standard exploding grenade. Useful against all enemy types though it does have a delay before it explodes.

Plasma Grenade- Does the same thing as your standard Frag Grenade but also has a dose of energy damage. Useful against all enemy types but you should save these for robots.

Pulse Grenade- A grenade that does solely energy damage. Useful against robots, turrets, and power armor.

Synth Relay Grenade- Spawns Synth Reinforcements
