Zerg does have an advantage over Terran but it must be taken advantage of early on.

- Rush early on before the Terrans have powerful units such as Ghosts and Battlecruisers.

- Attack often and in large numbers. Go for the tanks and bunkers 1st if you can.

- Sometimes, you may have to produce troops at your main base and all expansions. Send in troops from every base simultaneously.

- Plague some enemy units with a Deflier and immediately burrow it. Then attack him with your troops. His units will die very easily.

- Ultralisks can be used to charge into numerous ranged troops such as tanks and golaiths. Ultralisks have a lot of hitpoints which I take advantage of more than its strength.

- You'll need plenty of spore colonies if you believe that your opponent will be attacking with cloaked wraiths. If he uses cloaked units on defense, then be sure you've brought an overlord along.

- Scourges are useful in destroying enemy aircraft that your mutalisks cannot defeat. Mutalisks are fairly weak when used against the Terran airforce. Always send in more scourges than what is necessary cuz some tend to be killed before hitting a target.

- If you're destroying a command center, don't destroy it completely. Use a queen to infest it and you'll control the command center now! However, you can only make infested marines there. These guys do 500 damage when they explode!

- Do watch out for your enemy trying to nuclear strike your overlords. You don't want to lose such an essential and versatile unit. (Not to mention that you'll have to rebuild them before rebuilding any more units.)
