I always do this build for the sheer fact that I don't know anything better to do.Anyways,it is very good for 2v2's,especially if your partner is also Terran,because you can both build to stop something.It can also be turned into an insanely fast medarine,if you like risking rushes,that is.BTW,I wrote this with Lost Temple in mind,but any map with a choke or ramp will do,obviously.

Build SCV's till 8
Use the 8th to to build a barracks by ramp/choke (the idea is wall in)
Build a 9th SCV and use it to build a supply depot by the barracks.
Build a 10th,and set him to mining.
Depot should finish before barracks.Set him to mining.
When barracks is done,use that SCV to make another barracks beside the first,so as to complete the wall in (if its being done on a ramp)
Then get SCV's and marines,but just like 1 or 2 of each,and save 100 minerals.

Now you gotta decide something.If you think you are gonna be rushed,build a bunker behind the wall in and stick those mutha's in it.If your objective is fast medarine or heavy metal,build a refinery instead.

Continue building marines and SCV's as you see fit.If going medarine,try to have/have around 150 minerals when the 2nd barracks is done.Use that SCV to build an Academy.If Heavy metal,just wait till 100 gas and get a factory.Anyway,this is where the build stops,as you now have to scout and act accordingly to your opponents strats.Oh,and do get a Engineering Bay SOMETIME in this build.Many peeps are cloak happy,and scan is NOT enough to stop it.Trust me.

You may be wondering why the hell would this be any better for 2v2 than 1v1? Well,when you get comsat,scan the $hit F#@! outta them and see what they are doing.If you have played it for as long as I have,you can spot what strats are gonna happen (I'm not saying im good,because im not.Im just saying I have seen it all and then some).
Tell your opponent that you/him need to build a certain way to counter what they are doing.SOOOO,if its zerg and they are going muta or something,go Heavy metal (Goliaths,wraiths,valks,ect) and stuff like that.While one person is screwing the others strats over,you can feel free to build a nice rape squad and ledge or drop or plain attack in front,with your partners counter units backing you up,blocking whatever nastiness was meant for you.

I hope you get alot of use out of this build,as I have.It will lose a couple of times.You just have to practice and leave somethings out or build something else not listed.Just tailor it to your situation.

CreepColony's Opinion: Remember not to turtle, because that is one of Terran's weaknesses.
