in the shuttle -> turn around -> press Tab and write "fly" go forward till you reached buidlings and ground -> press Tab and wirte "walk" -> find your artifacts.
After founding all Artifacts do this:
Go in the Menu and open your save with the artifacts. Set 10177 to "4" like it was before you started (mine was 20).
Set your Player position to the position of one of your saves where Shepard is at the Citadel. (Just open the save editor 2 times and copy/paste it)
Also Change the Base Level Name.
Save & Start the game with the saved file. The woman asks you for a shuttle, just press no. Now you are in the Citadel with your Armor and a weapon. (funny and unexpected =D )
Go back to to the entrance and go back to Normandy. Now you should see Eden Prime. You can't land on it. Just leave the Planet and it's done.
