I don’t win much. See my strategies and find what’s wrong.
Terran: Marines+Medics=Dead base. Send in groups of Marines, with an equal number of Medics backing them up. Use Stem Packs with the Marines while the Medics heal them almost immediately. Goliaths are pretty much the only useful ground vehicle; Vultures have no useful abilities and Siege Tanks can only wreck REAL damage when the enemy’s defense is wiped out. Battlecruisers also suck; they take seven centuries to build, have low attack ability, move about as slow as a snail in molasses, and Yamato can only be used about once or twice. Wraiths rock, as well as Dropships and Science Vessels.
Zerg: When playing as the Zerg, a small section of the brain screams, “Zerg rush, Zerg rush.” The Zerg were made for speed; they move faster than any other race in the game, build and spawn much more quickly, and can level entire bases within thirty seconds or your money back. Build Zerglings early on, then rush the enemy base into submission while it’s still trying to build. If the game doesn’t allow rushing, though, then it’s all a matter of building big battle-esque units like Devourers and all those Scourge add-ons.
Protoss: Zealots are gods. Build tons of Gateways, send in tons of Zealots, and watch as your enemy is butchered. Once again, if rushes aren’t allowed, then it’s back to building big stuff. Dragoons, High Templars and Dark Templars aren’t that useful; they take too long to build and have no good abilities. Archons, on the other hand, can be used to full advantage in a match. Proton Cannons can make for an excellent defense, especially if placed close to each other. Besides that, I don’t have much strategy.
