get 7 scv's
with 7th make depo
get 2 more scv's
with 9th make a raz
when your 7th scv finish's make the depo make it build your 2nd raz
make 10th scv and build refinery
put 2 scv's on the gas
then save up 200 minerals and 100 gas for your first factory
when you have it build factory and make more scv's to mine and get gas
while this is all happening you should be making marines and getting stim and range upgrade
when factory is done get 1 startport and control tower
once tower is done make 1 dropship
load 8 rines in the ship and find your opponent's base by traveling at very edge of map once you
have found his base drop your rines right behind his minerals and kill all scv's probes or drones this probley will not kill him but it will slow him down dramiticaly
the win will be ez if you have destoyed his miners and cc, nexus, or hatchery. Good Luck!!

CreepColony's Opinion: Range upgrade may not be necessary, but stimpack will really help.
