Zerg vs Zerg is basically whoever is faster and more skilled will win. However, there are special tricks a Zerg players can only pull on another Zerg player.

- Take out enemy Queens and Guardians with Scourges. Guardians cannot hit air units so your scourges will survive long enough to hit the Guardian. Queens can parasite the Scourge, but it's pointless when the Scourge will also die when it hits the Queen.

- Destroy all of your enemy's overlords preferably with Scourges. Two scourges and one overlord all cost the same amount of net resources and the scourges will destroy the overlord. However, if you do this quickly enough and launch an immediate attack that takes out either their workers or their army (preferably their workers), then they'll be utterly crippled. They must rebuild their overlords before they can rebuild their workers/army.

- You can build stuff on your enemy's creep!! (I'm pretty sure.) However, it's rather pointless for you to bring over a drone and start building on his creep. Place the exit of a nydus canal on an unguarded portion of the enemy's creep and transport your troops there!! Muhahahahahahahahahahahahaha!!!!
