TvT 1rax FE

General Overview

This 1rax FE build gives you a strong economy, while staying reasonably safe from early Factory or Starport pressure.  It then transitions into Stimpack and gets your Bio upgrades rolling to hit a strong midgame Bio 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 very early Marine all-ins or Hellion pokes.  Therefore, the most important thing to scout is your opponent’s follow-up build.  Be sure to scan your opponent’s main base as soon as your 2nd Orbital Command finishes so that you can tell if Banshees, Widow Mine Drops, or a 1/1/1 all-in is coming your way.  Get an Engineering Bay and no more than 2 Missile Turrets per mineral line to deal with early pressure.  Rally all of your Marines (besides those in the Bunker at the front) in your main to deal with drops.


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 adding in some Marauders into the 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 Banshees or Widow Mine Drops if you do not see it coming and position your Marines correctly.

Favorable Maps

This 1rax FE is viable on every map except Deadwing because every map in the current map pool can be defended with one Bunker at the front of your natural.

  • King Sejong Station
  • OVergrowth
  • Catallena
  • Merry Go Round
  • Foxtrot Labs
