|關於an overview of alien blaster models in the Fallout series of games，參見alien blaster。|
Unlike the alien blaster, the Captain's Sidearm uses alien power modules instead of alien power cells. It has a silver finish to it, unlike the rusted alien blaster that can be found in the Capital Wasteland, and actually shoots out a spread of energy like a shotgun. Shooting the sidearm into the air will show the spread of the energy. Each time it is fired, it uses 3 rounds and sends 6 energy projectiles. Like the Metal Blaster, it will do significantly more damage outside of V.A.T.S. due to multiple critical hits. Although it looks like a pristine alien blaster, it can only be repaired by alien atomizers, alien epoxy, or vendors.
The Captain's Sidearm can fire a total of about 714 times, the equivalent of 24 reloads, from full condition before breaking.
- Alien atomizer - the common variant of atomizer found on Mothership Zeta.
- Atomic pulverizer - Although only slightly more powerful than the atomizer, the pulverizer uses only 12 AP per shot.
- Alien blaster - The common variant of blaster in Fallout 3.
- Firelance - Harder to obtain, yet slightly weaker than the blaster, the Firelance causes fire damage if the target survives the initial blast and is affected by the Pyromaniac perk.
