Replicant is a custom campaign for Starcraft 2 following the Protoss in 10 missions. You will encounter familiar characters such as Artanis, Vorazun and Alarak. But also some new ones.

This is a time of peace and prosperity for the Protoss people. Five years have past since Amon, the dark god was defeated. Since that time the rebuilding of Aiur has begun. Even though there is peace between the three races it is a fragile peace at best and now strange attacks has been reported through Aiur. Some Protoss report that the attacks are the work of.. The Dominion.
