The Alien crash site is found due north of MDPL-13 Power Station and northwest of the Greener Pastures Disposal Site.
Firelance, an extremely hard to obtain, yet slightly weaker variant of the blaster, the Firelance causes fire damage if the target survives the initial blast and is affected by the Pyromaniac perk.The weapon will break after 125 discharges, but will not jam until approximately 120 discharges giving it only one chance to jam. The alien blaster deals electrical damage, the only other weapons that do electrical damage are the Firelance, The Shocker, Jingwei's Shocksword, the Tesla cannon, the shock baton and the Captain's sidearm. 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). You will often be able to take down any foe you encounter with one well-aimed shot to the head. The alien blaster is one of the most powerful weapons in the game because a critical hit is guaranteed.
