The alien blaster is one of the most powerful weapons in the game because a critical hit is guaranteed. This weapon will often be able to take down any foe with a single shot to the head.
This weapon also has the effect of disintegrating any enemy killed with a critical shot by it (which is every shot for creatures weaker than most super mutants), identical to a laser (with the exception that the disintegration effect is colored blue instead of red).
The alien blaster can fire a total of about 125 shots, the equivalent of 13 reloads, from full condition before breaking, but will not jam until approximately 120 discharges.
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 Pyromaniacperk.
