Since im bored i'll write up a zerg start off for a 2v2 map....also works for 1v1 against protoss..
build up to 9 drones then get an overlord
use the cancel trick to get your supply to 10/9
by the time your overlord comes out build 2 more drones which brings you to 12/18...save up 300minerals hatchery.....11/18......get a spawning pool 10/18....get two more drones 12/18 and then get a gas chamber after that get another drone....12/18
by the time extractor comes out i send 3 drones there to get 100 gas after 100 gas i send em back to mine minerals....100 gas is for upgrade zergling speed.....pump out lings when until you hit 18/18....get an overlord.....make sure to micro well with your 12 lings.....by this time u get another hatchery probably expanded somewhere or still within ur base up 2 u.....make sure u scout their choke with lords so if u see a whole mass coming out and u know their out for u get sunks at least 2-3 depends....from here u choose ur destiny air or lurks do watver....if against 2v2 toss and zerg go mass ling and AIR! if u c terran and toss lurks but dont go techin or u get outmassed and killed straight off thats why pump lings and drones....Terran Zerg opponents hmmm depends on ur team mate if ur team mate is toss tell him to go STORM OWN ALL THE M&M saves ur arse! i personally think AIR! and mass sunks at the front....or u get ownedd by stim M&M if ur team mate is terran tank and M&M as ASAP....
You guys may have troubles with zerg many ppl ask when to build drones and i see a lot of ppl with not enough of them......After an attack which has devasted the opponent thats when u pump out 3-6 drones at once with the 2 hatcheris....if your attack isnt successfull......say if u have 3 hatcheries use the 3 for lings and save two larvae for drones.....
I CAN GO IN MORE DETAIL IF U WANT I CAN EDIT THIS IF U REALLY WANNA KNOW WHAT TO DO AND BUILD JUST REPLY!
