Multiple Games?

If I beat Factions or Nightfall, how is it possible for me to take the same character to Prophecies? If possible, are all of the missions possible to complete, or just some end ones?

All missions from all games can be completed by any one character. If a factions character you have to talk to the guardsmen in Kaineng Center. I dont remember which one gives you the quest to go to which campaign atm but you may as well pick them all up and then just complete the quest and you will be in the other game. If in Nightfall I believe you get the quests from Consulate docks... Also you will enter the new campaign part-way through, for example when you enter prophecies you will enter into Lions Arch, therefore if you plan to complete all missions you will need to backtrack. You don't need to beat the games in order to move onto the next one either. Hope I helped some. PM me if you cant figure it out from there.

Thanks a ton!

Everything you may ask about campaign travels is here.

You only need to be level 10 to travel to other campaigns.

You need to be level 10 to get to the Eye of the North expansion, level does not matter for the other 3 campaigns
