The atomizer is an alien pistol that is commonly used by alien personnel aboard Mothership Zeta. It has an average rate of fire and does relatively high damage when compared to other sidearms found throughout the Capital Wasteland, second only to scoped .44 magnums and their unique versions. It is also dead-on accurate with a 0 spread rating, making shots fire exactly on the crosshair for a 100 Energy Weapons skill user. The atomizer has an exceptionally high value-to-weight ratio (250 caps per pound at full repair), so scavenging the dozens of atomizers found in the course of Mothership Zeta's main quests can be a very lucrative endeavor. Like the alien disintegrator, it has a very high item HP, so the weapon does not need to be repaired often. An atomizer can fire 714 bolts before breaking.
The following is based on Fallout 3 cut content and has not been confirmed by canon sources.
Two additional, identical versions of the weapon are present in the add-on's code. Examined in the G.E.C.K. they differ only by their IDs, DLC05WeapPistolB and DLC05WeapPistolC. They are otherwise identical to normal alien atomizers and are even affected by the Xenotech Expert perk, but cannot be used to repair alien atomizers or their variants. Though not placed anywhere in the add-on, these weapons have been known to show up on occasion.
