The alien blaster in "Fallout 3" is one of the most powerful weapons in the game. Every shot guarantees a critical hit, often taking down enemies with just a single firing.
The alien blaster disintegrates the bodies of the creatures it kills. Its damage comes in the form of electricity, which is one of the few weapons in the game that use this type. Unfortunately, this weapon's lack of durability is its downfall, as it can only fire around 125 times before breaking down. It uses the rare ammunition of alien power cells. Players can find it at the alien crash site north of the MDPL-13 Power Station.
