Terran Mech vs Zerg

Today I will be telling you a terran mech build against zerg

Block off ASAP to stop early zergling pressure and do not be afraid to pull SCV's to repair

Basic Build

• 10 Supply Depot
• 12 Barracks
• 13 Refinery
• 14 Scout
• 15 Orbital Command
• 15 Marine
• 16 Supply Depot
• 16 Marine (2)
• 18 Factory
• 20 Reactor on the Barracks
• 21 Command Center
• @100% Factory
  
  • Switch Factory to Reactor
  • 2 Hellions (and continue production)

Mech Transition

• 27 Factory (2)
• Orbital Command (2)
• @100% Factory (2)
  
  • Tech Lab
• @100% Tech Lab
  
  • Siege Tank
  • Infernal Pre-igniter
  • Float Barracks out

Some things you need to know:

• Build the Factory close to the Barracks as you'll float it to its add-on.
• Build the Command Center in-base so you can float it out upon securing safe passage.
• Try to harass with any and all Hellions you have. Rally in new Hellions as you build them.
• Build the Orbital Command add-on before moving the Command Center out of your base to play safe.
• As you're playing Hellion-heavy, the Pre-Igniter should be the first Tech Lab upgrade you get. Although Hellions are not too effective versus Roaches, you should be able to successfully kite them until Siege Tanks are out.
