Mod, that allowes the player to work for Enclave as a secret agent.
What can the player do:
-talk the father into working for Enclave too
-find Geck, give it to Autumn
-convince Autumn that Eden is right and stop the inside conflict in Enclave
-put FEV into water
-re-program Liberty Prime so he will turn hostile to the BoS (while going to the purifier)
-get even with BoS (may be done in different ways)> 1.bring poisoned food which will kill most of the soldiers, 2.kill them silently in a ninja-style, 3.bomb the Citadel.
How will the player join Enclave? In Megaton in Nathan's house you meet a person who will recruit you.
I am already making such a mod.
It's called Enclave Improvement Project and allows the Lone Wanderer to join the Enclave through a lore-friendly quest chain.
To join the Enclave you must:
1) Ask Eden why he won't have Colonel Autumn use the FEV. Eden tells you that you can succeed him if you will, and thus it triggers the quest "Joining the Enclave".
2) Use the FEV in Project Purity.
3) Move to your player house in Megaton or Tenpenny. A holotape from President Eden instructs you to eliminate pro-Autumn resistance at Adams Air Force Base.
4) When you cooperate with the BoS and kill the Enclave at AAFB, you get to join the Enclave.
After you've done that, you can do a set of quests. One involves reversing the FEV's effects if you're a good character, and another deals with establishing Enclave outposts around big Wasteland cities.
The mod is technically ready for release, but conquering the Citadel causes save corruptions.
