Terran Lurker Rush
Submitted by Caspiar

1)4 starting drones mine (if you are fast, its better to choose which minerals they mine, otherwise time is wasted while they try to automatically find unoccupied minerals) buy the drones till you have 9 all mining
2)build extractor with 9th
3)buy 9th drone again
4)wait till you have 200 minerals, then buy pool
5)buy 9th drone again
6)get 3 of your mineral miners in the extractor
7)build overlord as soon as possible
8)upgrade lair
9)buy 3 more drones
10)build hydra den
(if you want, stick some defense somewhere in here, but I like to get my rush done ASAP, because I don't play on B-Net, and my friends suck at rushes , and never even try)
11)upgrade transport
12)upgrade lurker aspect
13)get 3 hydras
14)upgrade to lurkers
15)use 1 overlord to transport 2 lurkers to behind the minerals of a terran base, then kill the comsat if they have it, and kill drones, then move through their base

This works best on terrans but also works on protoss, because they do not have detectors at the back of their base usually. Also, it helps when the enemy is nearby. If not you need overlord speed upgrade
