Fallout 3 Krystal Mod by Burmecian

Burmecian has made a mod that allows Krystal to be playable in Fallout 3. The mod also includes a downed Arwing (which brought her there). The mod is apparently still being worked on, so it will likely improve over time.

Be warned, there are nude images of this mod on the images page. I have been told that you can’t directly make Krystal nude via this mod. Other work is required for that. Nevertheless, the possibility for adult content is there.
