• Zeratul must survive

Conditions for losing

• Zeratul dies

You start off with Zeratul, 2 Dragoons and 4 Dark Archons. Move your units south until you see some Terran Marines. Don't provoke them. Instead, have Zeratul move a bit more south until you see some Siege Tanks. Using Mind Control, take both of the Siege Tanks, preferably at the same time. When the Siege Tanks open fire, having your Dragoons move in too. Also take control of the Science Vessel there. Now, repeat the process by having Zeratul in front and Mind Controlling another pair of Siege Tanks when you see them. When you've acquired 4 Siege Tanks, rest your Dark Archons until at least 2 of them can cast Mind Control again. Now, move your Science Vessel southeast until you come to the Photon Cannons and an enemy Battlecruiser attempts to engage it. Move it back to your Dark Archons and gain control of it. Use the Battlecruiser to destroy the Pylon that powers the Photon Cannons. Now, move Zeratul to the two beacons and he'll tell you of his discoveries. Move on southwest, and when you get to two ledges, there will be enemy infantry on them. Put your Tanks into siege mode and your Science Vessel explore. The Marines will fall to Tank shells, so move past them for another beacon. Move southeast again and Mind Control the Battlecruisers you see, and the Siege Tanks as well if you have the time. Once you've gained control of them, destroy the enemy infantry and push southeast for the conclusion.
