Explosive

Explosive ammunition is, obviously, the type of ammunition that explode upon impact, transforming chemical potential energy into explosive kinetic energy.

Explosives are almost always more powerful the closer a target is to the center of its blast radius in Fallout 3. This blast radius is known as the Area of Effect, or AOE.

Examples of explosive ammunition are the missiles that are used by the Missile Launcher and derivatives, (in some opinions) the ammo used in combination with the Tesla Cannon, and, of course, the Mini Nuke ammo which gets launched for several metres, unlike a grenade that is hand-tossed.

There are 3 different types of explosions in Fallout 3: regular, pulse (indicated by the blue energy field that is emitted, great against robots) and plasma (big, magnetically-sealed explosions which produce a big, green ball-like explosion that covers a few metres upon explosion) with a big chance of crippling allies and/or enemies' body parts.
