Every match on the Zone is won or lost in the first three minutes. Whether you drop onto Lost Temple, Hunters or Big Game Hunters, the player who fumbles the opening rarely recovers. Here are the core build orders for all three races. Drill them until you never think about them again.

2-Rax. Two Barracks, Marines out the door fast. This is the rush that would make Jim Raynor proud.

• Build SCVs non-stop, Supply Depot at 8.
• First Barracks at 10, second Barracks right after.
• Pump Marines and pressure before your opponent has a wall.

1-Rax FE. One Barracks, then Command Center. You trade early punch for a second mineral line - safer against Protoss, greedy against turtles.

9-Pool. Spawning Pool at 9 Drones for fast, aggressive Zerglings. On tight maps like Blood Bath this can end things outright.

• Drone to 9, drop the Pool, keep an Overlord queued so you never choke on supply.
• Six lings out first, harass the worker line.

12-Hatch. Expansion Hatchery before the Pool. More Drones, more larvae, a bigger swarm later - Kerrigan would approve, but scout or you die to the rush.

2-Gate. Two Gateways on one base, Zealots forever. The classic Templar answer to an early attack.

• Pylon at 8, first Gateway at 10, second Gateway soon after.
• Pump your Zealots out and push, keeping a Probe scouting.

Nexus-First. Expand before your Gateway. The greediest economic opening in the game - Tassadar's long game, if you survive the early minutes.

Golden rules:

1. Never get supply-blocked. Depot, Overlord or Pylon comes before you need it.
2. Always be building workers - SCVs, Drones and Probes are your whole economy.
3. Scout by supply 10 so you know which build to counter.

Learn one opener per race, then master its greedy variant. When Brood War lands, these same builds carry straight over. See you on the ladder.
