 * Mission Background
 * You, the Cerebrate, have grown powerful enough to warp travel with the Swarm to the planet Char, where the Chrysalis is to be nested. However, lingering Protoss forces will try to block your exit from Tarsonis. Your objective is to get the Chrysalis safely to the Beacon so that it may be sent to Char.

When this mission starts, you are given two Drones, three Hydralisks, two Mutalisks, and six Hunter Killers. The Hunter Killers are powerful versions of Hydralisks that have been given to you by Cerebrate Daggoth, and must be awakened by sending one of your units near them.
 * Walkthrough

Immediately get your economy going--build at least 10 Drones for mineral gathering and then about four more for gas. Meanwhile, group the Hydralisks and Hunter Killers together and have them guard the border of your base (put them on Patrol if you wish). When you have the resources, build a Hydralisk Den, convert your single Creep Colony into a Sunken Colony, and morph another Creep Colony (to be converted into a Sunken later on) in the southern part of your base. You may also research Burrow, but it's not critically important in this mission.

Build up a good number of Hydralisks, and also make some Zerglings (don't go crazy with them though, as they're only useful against Photon Cannons and Dragoons). While building air units (Mutalisks and Scourge) isn't a necessity, if you have the time and resources go ahead and make some if only to explore the tech tree a little bit further and get to know said units better. The Protoss will attack your base once in a while, so put any finished units near the three main entrances to your base (south, southeast, and east), and throw in some Sunken Colonies for good measure. Enemy Scouts can be countered fairly easily with many Hydralisks, so there's no need to build Spore Colonies.

When you have about two full groups of Hydralisks (you may include the Hunter Killers here), take them plus any Mutalisks and Zerglings you may have and hotkey them accordingly. With a Drone, pick up the Chrysalis which is on your own beacon (to do this, just select a Drone and right-click on the Chrysalis).

All-in Rush.
