StarCraft: Brood War/Protoss Mission 6: Return to Char
|New Enemy Units||Zerg Lurker|
|Retrieve the Khalis Crystal with a Probe or Drone or do enough damage to the Overmind to send it into remission|
You start with two bases in this mission; a Protoss base and a Zerg base. They are very near each other, so it is easy to support each base when you need to. Once you start the game, you will notice that your Protoss base has many mineral fields, but does not have a geyser. Your Zerg base does have a geyser, but it only has a five-mineral field patch. You need miners from both bases to establish your economy.
Now take a look at your starting Observers; the one on the west side shows you two burrowed enemy Lurkers, and the one on the east side shows you a small mineral patch with a geyser. You have another Observer near your Forge. Lurkers are large-sized ground units evolved from Hydralisks, and they will attack you while burrowed. The Lurkers will probably make you jealous because you can't make them yourself... yet.
You should expand at your small base quickly for more gas. It is ideal to build a Zerg base there, since the area is both closer to your Zerg base and you can get Drones more quickly than Probes. You can support this base with Photon Cannons, but build them up the cliff.
Your next expansion should be to the west, where it is occupied by Orange Zerg. A group of reavers and hydralisks are necessary. The reavers can take out the base by themselves, while the hydras are there to provide cover. Then, get a nexus or hatchery going.
Once you have enough resources coming in, start building your attack force. Place some photon cannons by the entrance to the expo. At this point, it is probably easier for you to strike the Overmind than to go for the Khalis Crystal. That is because most of the land to the south (right before you get to the Overmind) is empty, if you travel by air. However, travelling via the ground is much more difficult to do. Therefore, you should plan out an carrier attack. With the surplus of vespene and minerals, get twelve carriers. You can bring in an overlord for detection and an arbiter for cloaking, but they are not necessary. Place the carriers next to the new expo and have them march southwards. Make sure that air attack and air armor are at level 3. In addition, get twelve corsairs and make sure both disruption web and Argus Jewel (+50 corsair energy) have been researched. A force of this size will overwhelm the zerg protecting the Overmind in a few seconds if you micro carefully. Head south from the new expo and stay out of range of the spore colonies on the cliffs to the right. Use the corsairs to protect the carriers from mutalisks and scourge as well as using disruption web on any spore colonies between the strike force and the Overmind. Other than that, a force of this size is enough to destroy the Overmind with ease.
 Alternate Strategy
As above expand as fast as possible to the second geyser below the zerg base. But you can almost ignore the whole protoss base and everything west of it. Just put enough units/cannons on the west entrance to fight off the occasional few hydralisks coming that way.
Now build 3 hatcheries and keep producing hydralisks, don't forget to upgrade them. Two or three groups of hydralisks should be enough to push at the brown zerg player to the south. You should send all hydralisks produced in your base to support the attack. Then you should be able to clean the winding path to the Khalis crystal with ease. Then just send a drone there. This strategy is probably faster then going after the overmind.
