Xenotech Expert

Xenotech Expert is a perk which is added to Fallout 3 in the Mothership Zeta add-on. It increases the damage done with alien weapons by 20%.

Obtaining the perk
To get this perk, you must find a "shooting range" in the weapons lab  (a room with an alien atomizer and an alien disintegrator next to a switch). The ranges are in approximately the center of the map north-to-south, and on the eastern side. Activating the switch closest to the door summons brahmin, while activating the far switch teleports enemies abducted by the aliens to a second range.

In order to get the perk, 10 enemies must be killed with alien weapons consecutively. There are four types of enemies at the second range:
 * 1) Raiders
 * 2) Yao guai or deathclaw
 * 3) Sentry bots
 * 4) Giant or albino radscorpions

Affected weapons
This is a list of weapons that are affected by Xenotech Expert. All alien weapons are affected except the Electro-Suppressor and the unique Captain's sidearm.

Bugs

 * It is possible for the perk not to trigger, even after several switch activations. To remedy this, simply save and then load the save. After loading, activate the switch again and the perk should unlock.
 * It is possible for the perk to trigger on its own just by letting the raiders and other enemies kill themselves.
