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
To get this perk, the player character 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

Additionally, the player character does not have to kill any enemies. Rather, spawning them through the button and letting them kill each other enough to meet the required amount is enough for the perk to be obtained.

It is advisable to remain hidden, however, as many ranged enemies will choose the player character as a target over their fellow captives.

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.
