I should warn you, this is an extremely poor build (very cheesy), with little or no chance of winning. It hopes to catch your opponent unaware.
The build itself works something like the following:
- 13 Gas
- 13 Pool
- 15 Roach Warren
- 17 Metabolic Boost
Its a derivation of the old 14 Gas/14 Pool builds, except that you go for a very early Roach Warren, don't build more than 15 Drones, and all in around ~3:45. You use your Roaches like a Baneling bust with lings to back up
I really don't recommend it, its largely inferior to the kind of pressure you can bring with a 15 Expand Roach/Ling build at the 6 minute mark. What's even worse it teaches you very bad habits (late or no expansion) and actually is amazingly weak against any standard play.
