1. Send 4 drones to minerals, build another drone with the 50 giving minerals, also scout with your overlord.
2. When the drone is finished wait for 150 minerals and build a spawning pool.
3. When the spawning pool is morphing build 2 drones, each when, right when you get 50 minerals for each.
4. When the Spawning Pool is done, there should be 3 larva, morph them into zerglings, when they are morphing, one larva should pop out morph that into an overlord.
5. Attack your oppenant, with your 6 zerglings, your oppenant should be dead, if not, atleast slowed him down somewhat.
6. Once your overlord is done, there should be 2 larva morph them into drones,
7. When the drones are finished build two creep colonys, and morph them into sunken colonys.
8. While they're morphing another two larva should be ready, morph them into zerglings, and send them infront of your colonies...
9. morph another two larva into drones, one making an extractor, another one, sent to minerals. Also get another Overlord
10. morph about 3 more drones, sending them to gather gas, once you have enough gas to morph Hatchery into a Lair.
11. wait for enough minerals to build 2 more sunkens and a hatchery.
12. Get more Overlords, and when the Liar is completed morphing, build a spire.
13. get more lings, and more overlords, get spores if you want.
14. When Spire is completed build 6 mutas, at your two Hatcheries, and attack his MINERALS,
15. Send in the Lings, if you have them...

CreepColony's Opinion: Very cheesy rush strategy.
