Heres my ending- you helped: The Brotherhood, Arcade, NCR, Lily, Boone, Got a new Brain for Rex from the Legion, Helped ED-E using the Brotherhood, and also helped the Bright followers.
This is the seen leading up to the Legion assault on Hoover Dam-
The Brotherhood is Relaxing drinking beer with some NCR soldiers reminicing (Joking around) over the battle of Helios 1.
The Snipers of First Recon are taking positions on a nearby tower making up a new drinking game. You kill a legionary you take a shot, you miss you have to go for a head shot and take 2 shots.
Lily and a whole bunch of Knight kin appear out of now where with energy swords and yells over "Hi deary, this is going to be violent and really don't want you to watch."
Boone is shooting birds out of the sky above the legion camp hoping a dead bird will land on some unsuspecting legionary.
------THE BATTLE:
The battle starts off and the Brother hood is doing trick shots with their laser weapons mean-while you see the 1st recon sniping and take shots of whiskey after every shot, Boone enraged the ravens he was shooting at and so there attacking legion soldiers to. Rex is swimming across the river and, is let into the legion camp because he was formerly owned by caeser, invokes an uprising with the other legion dogs that aren't well fed. Its' been about a week and a half now sense ED-E left the brotherhoods care and took off towards east, you hear 4 vertibirds flying overhead and a loud crash. Then you hear it "Liberty Prime online, objective: Destroy all communist chinese invaders." It's Liberty Prime with and is using ED-Es Optics to function properly again.
After a couple of hours of intense fighting the battle is a close stailmate. . . That is until. . .
Jason Bright *over the loud speaker*: " LOOK WHAT WE FOUND!!! " ZAAAAAPPPPP
About an hour or so after Bright and his followers took off they were tractor beamed aboard Mothership Zeta and used it to help at the Dam, except they crashed into it . . .
