9 Food send scout
10 food supply depot( I normally have another scv being built)
Just focus on the scout until the depot is done
Rax and then build 3 more scvs then a gas ASAP. But, do not fill the gas because of the trick to this build.
You then need to build another rax with 2 maybe 3 marines being done at the point
EXPAND and make sure you have 4 marines
Note: You can make a few more marines after your first 4
You also need to get a bunker in a place that defends your main and natural the most.
By now You will definitely need a supply depot and I just try to fix it into these transactions.
if you aren't at 100 gas when you second rax is 2/3 the way done go ahead and fill it otherwise wait till after the first factory.
Build a factory and start putting a tech lab and reactor on your rax.
You now need another gas and your expansion should be done soon,
At this point you should be
Now you need the Starport and and to get stim all the while building more scvs. Also put a tech on your factory now.
Now, you econ should be pretty solid at this point with both expansions with a workers(second with atleast 5-7) Now just start building units. Build your Medivac then siege depending on whether you scout and early attack or not. Just start making marines and a few marauders. And remember to put a reactor on your starport.As well as start combat shield
at 8:00 you should make two engineering bays and quickly follow that with a armory.
Put a full gas in your natural and then you have two options. You can get a third or put down 3 more rax.
With the rax go 2 reactor 1 tech. Either way by 12:00ish you should have both. And then just add another factory and then you try to transition into thor support or hellbats depending if you want to use more gas or not.
Again this is a rough build and the timing are not exact, but these are the quickest or some of the quickest timings I could get out of this build. I am upper Silver on the AM server so there is room for improvement. Well, hope you liked my build and let me know if you were able to get faster timings and or made interesting changes =)
