If you are an impatiant person, simply fastforward the replay to the elapsed time 41:00 because that's when I finished the glitches and at that point zerglings pop out of thin air. This is a map I created with fake gas on the main bases and real gas outside to have fun with when bored. legodude522 joined my game not knowing how to get to the gas. I played with him and even offered him an ally which he refused. Then I decided to attack him using ONLY zerglings (but I was Protoss). To make things interesting, I used the Mobile Nydus Canal and Permanently Cloak a Zerg glitches to make it seem like Zerglings pop right out of the ground! To see this effect, unshare my vision in the replay and look at only legodude522's vision. You can also download the replay and maps for it from this website:
