Lurker Attack
An excellent strategy against Terran.
-Start by building a drone, and putting the 4 on minerals.
-Continue building drones and putting them on minerals, until your 9th drone is out. Make him into an extractor.
-Build another drone and an overlord. Morph that drone into a spawning pool.
-Make more drones, putting 3 on gas, and the rest on minerals. Also, build 1 sunken colony, in case your opponent wants to scout with a marine.
-Once you have 100 gas, make your hatchery into a lair. Also build another overlord.
-Once you have 50 gas, make a hydralisk den.
NOTE: Lurkers costs a lot of gas, so if possibe, build 2 geysers.
-While the lair and hydralisk are building, make 6 zerglings.
-Once the den is done, build 3 hydralisks.
-When the lair is done, quickly upgrade lurker aspect.
-When hydralisks are done, build lurkers, so you have 3.
-Send your 6 zerglings to fight their defense, which is probably 1 or 2 bunkers. Burrow your lurkers to help your zerglings, and once their defense is gone, go for their workers.
-They will probably lift off, which means they are done for.
-Build a few hydralisks to chase the flying buildings.
