I liked the idea of Androids in the game, but I felt that the game was very lacking in the lore and in the Androids themselves. I set out to create more realistic Androids and put them in the game. If you use TTT's "Companion Share And Recruit" mod (http://www.fallout3nexus.com/downloads/file.php?id=12106)
You will be able to recruit these Replicants.
There is a small settlement which will be on your world map that has around 5 Androids living in solitude. There is also one hiding in Megaton and two residing at Tenpenny Tower.
This is a Beta release, I plan on doing much more to this.

Features:
Androids that explode into sparks and metal debris when destroyed.
They emit an electrical sound when hit with projectiles or other weapons.
The Males speak in a robotic voice with quite a bit of dialog. The females speak in a normal voice since they were originally created as "pleasure models"(Lore)
(Lore/story)Androids gather in radiation from their surroundings as power, and are able to turn their entire right arm into their weapon, emitting an intense beam from their right index finger(Feature).

I plan on adding a LOT more to this mod enjoy the BETA.

Feel free to tell me what you think, what features you would like to see, etc.

Excellent idea ! Now if only you could make their eyes glowing red or somehow different than other normal people's...
