[G] TvP FE -> 4Factory MTH, inspired by Byun

This is my first "guide", and it is now comprehensive. I am a High Masters Terran on NA. So far I've been successful with this build, but I would not recommend it as a main staple build... just something you have fun with every once in a while. I personally don't see this working on small maps, and have only tried it only cross positions, on maps like Tal'Darim Altar, Shakuras Plateau, and maybe Antigua Shipyard. With that said, this is a very strong build.

Build Order
10 Supply Depot (near CC, not choke)
12 Barracks (when the scv finishes Barracks, this is your scouting SCV)
15 Marine (only one for now)
16 Orbital Command (that scouting SCV should be heading out)
17 Command Center at natural (to time this right, pull an scv when the marine is 50% done, send it to natural)
17 Supply Depot
17 Marine (this one is delayed, but constant hereafter)
22 Refinery
22 Refinery
24 Bunker (can slap down at 23 if you aren't comfortable)
25 Factory + Orbital Command
29 Reactor on Barracks + 3rd Refinery at natural
31 Supply Depot
34 Supply Depot
34 Tech Lab on Factory
37 Tank + 2x Marine + Siege mode (constant Tank+2marine from here on out)
42 Supply Depot (constant supply depots from scv from now on)
~55Food, once you've started your 2nd tank, throw down 3 factories at once.
~You also need to start building 2x supply depots constantly now
Once the 3 factories finish, build 3x Reactors on them + Blue Flame upgrade (this massive gas dump will delay your 3rd tank a little bit)

When you push out at 10 minutes you should have:
~100 supply, consisting of
20 Marines
3 Siege Tanks + Siege mode
6 Hellions + Blue Flame
and by the time you reach your opponents base another 6 hellions should have caught up (they're so fast) and 2 marines and another tank straggling behind. The speed of hellions is really the strength of this build. They reinforce fast, they can dart up ramps for vision, and they can quickly harass a mineral line away from your main push.

This is not the "best" execution of the build. I make an early push with just marines and tanks that I feel confident will do damage if hes teching too hard, unfortunately I didn't send 1 marine ahead of my army like I'm supposed to... and got caught out of position. Then when I sieged on the low ground I didn't have the hellion I needed to sprint up the ramp for vision and had to pull back. Barf. If you want a better execution replay, check the GOM VOD, or check back here later, I'll try and upload a better one.

Vs 4gate: hopefully you have enough bunkers + scv repair + wall off until siege mode arrives
Vs Voidray: continue with siege mode, but get a viking asap, possibly even swapping starport with the reactor rax if you still have healthy marines (2x viking or viking+medivac)
Vs DT: hopefully you haven't muled too hard, get a Raven asap. If it's that dire of a situation swap the starport for the factory techlab and cancel siegemode. If you're not sure if it's a DT, you can afford the 325 minerals to make an engi bay + 2 turrest (1 at each CC)
Vs Colossus: I actually haven't seen a 1base colossus build on a big map in a long long time... so... you should be safe with siege tanks + vikings OR banshees, just keep your marines away from that colossus!
Vs Anything on a small map, you're dead.
Vs What else is there that isn't an expansion build??

I delay the tanks for reactored hellion scouting/harass and defensive marauders. The one thing I like about this game is the extra barracks I build and float over to gain vision of the high ground + extra tank range. The biggest criticism I'd have in this game is I positioned my tanks poorly outside his natural, I could have done a better job.

Basically I just slammed out the build order, positioned myself properly, and then started to lean on him till he caved and lost. Pretty easy win.

Then I scouted an early robo + colossus, and it took me longer than it should have to throw down the starport. He tried to flank my army, so I just pounced on the position to prevent his retreat. KEY NOTE: I DID NOT PUSH INTO HIS BASE. I just separated his army from his base, and then sent in the hellions to harass. However, afterward he caught me out of position and raped my army. Bad. Didn't panic, came back, won in a long game. However, I noticed he was going very stalker / colossus heavy, so I decided getting some marauders might be a good idea. I'll be honest, I don't have a lot of late game experience with mech, so some games I end up transitioning into a mech/bio hybrid, and just abuse the positioning power of tanks, and the zealot/ht/probe roasting power of hellions, WITH bio.

I delayed his expo with an engi bay, and then feared he might just 4/5gate me instead of actually expanding, so I threw down an extra barracks. I later scanned to see that he did in fact expand, so I just used the extra barracks for addons, not a huge deal.

Later he catches me in the middle of the map as I'm pushing, and when I see his army I decide it might be better to just take map control and play safe instead of going for the kill, which is a great strength of this build. At around 22/23minutes, he engages me with a maxed protoss deathball, but my 3 emps + 8 sieged tanks and 70 supply of hellions melt his shit pretty fast. Splash damage ftw.

He catches 3 of my tanks unsieged, and has 3 colossus of his own. Somehow the engagement still goes in my favor, and I probably could have ended the game at 13minutes but I didn't realize how badly I had beat him.

He goes mass blink stalker, which I'm forced to defend with hellions, which means neither of us is killing eachother very fast. After the second blink stalker bullshit I said fuck it and started making/upgrading marauders. I should have denied expos / hellion harassed his eco more in the late game, but other than that a solid game. Oh and he desparately tech swaps to void rays and goes for a base race, but it fails.

So he 2gate VR expands... Keys to defending this kind of crap: unit positioning! Just run away from the VR until he over extends, then engage. This will both minimize losses and delay for your viking. It's important to still get siegemode asap, because if they bring the gateway units too, you're gonna need the siege range.

After that, ezwin.
