Upon the Shadowed Seas is the fifth mission of the Alliance campaign in Warcraft II: Beyond the Dark Portal.

Mission briefing[]

Having fortified your position on the Hellfire Peninsula where the Portal is located, the time has come to establish a fleet to attack the surrounding clans. The Orcish shipyards of Zeth'kur lie nearby, and for our plans to progress you must destroy them and the ships of war that are stationed there.

While the Horde has been stunned by the ferocity of your attack, our presence here has driven the clans to new heights of fury. You will be unable to maintain this foothold for long against their numbers, so your victories must be daring and swift.
