TvZ 1rax FE

General Overview

This 1rax FE build gives you a strong economy, while staying safe from early Zerg pressure.  It then transitions into Stimpack and gets your Bio upgrades rolling to hit a strong midgame attack.

Build Order

  • 10 – Supply Depot
  • 12 – Barracks
  • 16 – Marine (only 1)
  • 17 – Orbital Command
  • 17 – 2nd Command Center
  • 17 – Supply Depot
    • Resume Marine Production
  • 21 – Bunker at Natural
  • 22 – 2 more Barracks and 2 Refineries
  • @100% 2nd Command Center, start Orbital Command
  • @25 Gas, start Tech lab
  • @100 Gas, start Stimpack Research
  • @100 Gas, start 2 Reactors
  • Benchmark: When you start these Reactors (@6:15ish), you should have 10 Marines and 28 SCVs.


This 1rax FE gets a fast Bunker at your natural expansion, so you can defend all early Speedling timings without worry.  Note though that positioning your Bunker close to the mineral line will help cut down the time it takes for your SCVs to surround and repair it – making you a lot more safe than having a Bunker defending the front of your natural.

However, if you still want to SCV scout, then be sure to spot your opponent’s Extractor timing.  Knowing whether or not your opponent is getting Zergling Speed is important for knowing whether or not your opponent has the possibility of applying early pressure (whether it be Roach, Speedling, or Baneling).


This is a macro build that gives you Stimpack and a lot of Bio, so the most common transition is continuing into more Bio by getting an Engineering Bay for +1 Infantry Attack, a Factory for later Reactored Medivac production, and going for a Marine/Marauder/Medivac/Mine unit composition.

Pros and Cons

This build is a heavy macro build, giving you a strong economy and infrastructure for the midgame.

However, it is somewhat weak to early aggression such as Roach all-ins if you do not see it coming and repair your Bunker with SCVs on time.

Favorable Maps

This 1rax FE is viable on every map except Deadwing because the natural expansion’s mineral line on every map in the current map pool can be defended with one Bunker.

  • King Sejong Station
  • Overgrowth
  • Catallena
  • Merry Go Round
  • Foxtrot Labs
  • Nimbus
