In Fallout 3 to get the wedding in Rivet City is to get ant Pheremons from the Giant Queen Ant, Supposilvely in the Antagonizers lair just north of canturbury commons. Then get the pheremones and give them to that girl that loves Diego. (I can't remember her name).
you go around asking people in rivet city
The chief guard in Rivet City, (known as Harkness) can be found usually in the Rivet City Market area of the ship. If you have not entered Rivet City yet you can go to the intercom near the edge and talk to Harkness and he will connect the bridge for you.
you have to complete the quest (The Waters of Life) to get access to the Citadel. http://fallout.wikia.com/wiki/Portal:Fallout_3
I dornt noo how to dop itnto rvent city. Maybe you could go to rivet city and then ask harkness for directions. (go up that metal thing and talk into the intercom)
Go Through Anacostia Metro Station Near Rivet City, Raiders Are In That Metro And The Occasional Feral Ghoul, Head Towards Museum Station And You Will Exit By The Washington Monument Then Just Next To It Is The Science Museum
Go to Rivet city in fallout 3 then go to the tunnels next to it :note that there might be enemys there like talon company: go across to the other side or go down and far to the side in the ground I cant remember:note there are supermutans there: Its hidden good so make sure you check the place clean. you need to have the lockpick skill of 100 or take the quest started in the underworld hospital called rileys rangers. thx and bye!!!!!!!!!!!
when you find out were your dad is get him back to rivet city. spoiler in between (not important) he will tell you to find a G.E.C.K go to scribe rothchild (i think) in the citadell. find out which vault contains the geck. go there and get the geck. get ambushed by the the enclave. 0.o make important choice. go to citadell for the epic war. jeese <pant pant>
Next to where the bridge should be on the platform, there is an intercom, just talk into it and they should move the bridge for you, this can be done at the start of the game so you shouldn't have any trouble here.P.S a guard will also stop you as you cross the bridge to go onto the ship, just tell him you are there to see your dad and he should let you past.
I think so:)
I Wrote this just go to my wall and answer it
When you get purified water x5 from your Mr. Gutsy robot (Megaton or Tenpenny Tower) go outside and give it to the man who needs water wait till you get your next load and give again. There is also a begger named Carlos, outside Rivet City, you can give him purified water to increase yoy karma. (the water can be found in First Aid box's, fridges, bought from traders etc. not just Mr Gusty) Talk to Father Clifford in Rivet City's St Monkia's Church, each time you give him a donation of caps for the church your karma increases.
I havnt played fallout 3 in a while but im pretty sure its near the capitol building and the ghouls hide out if you still cant find it search for Fallout 3 flash map in a search bar The Museum of Technology is near the Capitol building. Be cautious before going in though as there are loads of super mutants.
