This is a Terran build, because I find that Terran are very op atm. This build is currently unbeatable.
This is how I execute it:
1. Reaper
2. Marine
3. Hellion
4. 2X Siege Tank
5. Pylon
6. Medivac
7. Dingle
8. 2X Viking
9. Pylon Upgrade
10. 3X Siege Tank
11. Pylon Upgrade
12. 4X Thors
13. 2X Siege Tank
14. 2X Viking
15. Pylon Upgrade
16. 4X Battlecruiser
17. 2X Viking
18. Build 2 Upgrade buildings
Upgrade from now onward. I always upgrade the plating first, rather than the weapons.
If you know there is a push coming then build 2 Chelupa Canons. NEVER nuke in the early game unless its a 'do or die' situation.
The ONLY way you can loose by doing this build is if you have NOOB team mates or you get cheesed.
