How to get to Atlantis

[pmatt00046]

Do I have to finish the previous Titan games in order to reach Atlantis?

Travel to Rhodes in Act Four. Go to the first area called “Asomata” (From the portal, go down the stairs to the right). Talk to the NPC named “Marinos”, I don't believe you have complete it just get to the area and talk to the NPC.

You unlock Atlantis very early in Immortal Throne...so you do have to beat the original game. But you can play it before or after Ragnarok or finishing IT. Personally, the first island in Atlantis is much harder than IT, at least on your first play through, so you might find it easier to play through at least some of IT and get a few more levels/better gear. I would certainly play Atlantis before Ragnarok, Ragnarok has better gear drops.
