So over the past 3 weeks Ive done a lot of research for the Enclave and Ive put a lot of things together that makes sense of why the Enclave could return. This will involve info from Fallout 3 and New vegas. Also some information from Fallout 2. So we all know that the Enclave have been taking hard hits form other factions in the fallout universe BUT! according to the eye bot in Fallout: NV ED-E the Enclave have an outpost in Chicago. That information is from Whitley a researcher at Adams Air force base.
He states that the enclave eye bot needs repairs so get this eye bot to Navarro which has been destroyed. Although the recording may be old Whitley also states the Enclave have and outpost in Chicago. Now heres my point: President Eden states on Enclave radio in F3 that the Enclave are trying to take over the east of the U.S.A. The city of Chicago is in the east of the U.S. So this clearly means that the Enclave have some sort of outpost and maybe even have a civilization in Chicago. So now you know what
Im saying. The Enclave are still out there everyone. There is no reason to think they are dead.
If you are to use this Information I have gathered please give me some credit by my account name and this forum. Ive worked for hours on researching this information so thank you for reading all of this.
