Pulse Grenade (Fallout 3)

A Pulse Grenade is an electromagnetic weapon that creates a large, crackling blue spherical pulse, dealing only minor damage to biological creatures, but far more major damage to mechanical targets such as Robots and Automated Turrets. In addition, most robots are disabled for a few seconds by the burst, leaving them open to attack.

Tactics and strategies
Thrown grenades are affected by physics; they may bounce or roll unexpectedly if not thrown carefully. However, in game physics can also be used to your advantage; such as throwing grenades through doorways or bouncing them around corners to attack enemies who cannot see you.

It is best to use a grenade on groups of enemies at chokepoints such as doorways or stairwells. Grenades are targetable in V.A.T.S. Thus they can be shot out of the air, and shooting them whilst they are still held by the enemy can detonate them. Grenades can be thrown point-blank in V.A.T.S due to the sharply reduced damage taken.

A grenade that has been thrown toward you will show up on your HUD as a red arrow denoting its direction relative to you. 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 an NPC by passing one from your inventory to the NPC's inventory via pickpocketing. This will kill the NPC, regardless of how much health he has, making the Pulse Grenade far more deadly against a single biological target, whilst other targets caught in the blast radius will only be dealt minor damage, in contrast to other grenades.
