The alien blaster is one of the most powerful weapons in the game because a critical hit is guaranteed. You will often be able to take down any foe you encounter with a single shot to the head. Enemies killed by a critical hit from this weapon are disintegrated into ash, identical to a laser with the exception that the disintegration effect is colored blue instead of red.
As with the alien blaster, the ammunition used by the pistol is also unique, meaning the 140-250 alien power cells found on the alien captain cannot be found anywhere else, limiting the use of the alien blaster.
The alien blaster can fire a total of about 2495 shots, the equivalent of 250 reloads, from full condition before breaking, significantly more than the 222-272 cells the player can normally find.
The alien blaster is found just north of Horowitz Farmstead, but is only available to players that have the Wild Wastelandtrait. If the Wild Wasteland trait is not chosen, the YCS/186 Gauss rifle will replace the alien blaster.
The alien blaster is found on the alien captain, along with 140-250 alien power cells. The captain is aided by two other aliens, all 3 are armed with laser weapons.
The alien captain will have this weapon in his inventory, but will not use it against the player.
Except for cut or unused weapons, the alien blaster has the highest in-game critical multiplier (100%) and therefore guarantees a Critical Hit regardless of the player's Luck stat or critical chance modifiers.
Synergises well with the Better Criticals perk, considering every hit is a critical hit, therefore every shot will have a 50% increase in critical hit damage.

xbox360 Be careful when putting the alien blaster into ED-E's inventory; sometimes it will replace its standard weapon with the alien blaster as would any other companion but, as E-DE can't physically equip the weapon, it simply disappears from E-DE's inventory and its standard laser blasts become the distinctive blue energy blasts of the alien blaster. It's impossible to get the alien blaster back when this occurs without loading a save from before the weapon was given. [verified]
