It increases the damage done with alien weapons by 20%.
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.
There are four types of enemies on second range. At least one of each type must be killed (by yourself or another summoned creature) to get the perk:
It may take some time to get one of each from the last three groups.
This is a list of weapons that are affected by Xenotech Expert. All alien weapons are affected except the Electro-Suppressor.
- 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.
