Here's a few starcraft 2 build orders for shits n giggles
5 Roach Rush (5RR)
Looking into other early options for zerg, I've come up with a very good opening against both terran and protoss: the 5 roach rush! It's capable of breaking into your opponents' base early on without going all-in. If it fails, one injection-round of drones and you're usually leading in the worker count.
Banelings are great, but way too expensive to use every game. Taking down a supply depot or pylon costs 250/125, and you have to have fighting units on top of that! With the 5RR, the roaches pull double duty by destroying the depot/pylon and still being around after it's gone. Not to mention they are fantastic against early zealots/marines.
