Rush Defense | Challenges SC II: WoL Guide
Last update: 11 May 2016
This challenge is split into two phases. In the first one, you have to fight off an attack of Zerglings, preparing defensive structures as fast as possible. You will have an identical task later on, when Protoss Zealots will attack.
As for the Zerg invasion, they can be very easily stopped by going down the map and placing Barracks in the middle of the passage. With the two other SCVs, build Supply Depots on both sides, just like the game advised in the previous challenge.
The Barracks surely won't be finished before the Zergs arrive, but that doesn't matter. Repair the damage done by the attackers while waiting for the first Marine to come. Afterwards systematically keep on training new ones, until you deal with all the Zergs.
Afterwards it's time to deal with the Protosses. Begin with building Barracks once more, but his time place them so that they're the leftmost Terran building. There's no way of training a Marine before the first Zealot comes, so this building will receive all his rage.
After you the building's finished, begin placing a Bunker behind it. Repair the attacked Barracks with the SCV and once the first soldier appears, keep running from the Zealot while waiting for the Bunker to be finished. Once you're safe inside it, you can pretty much feel like you've completed Rush Defense.
Keep on training new soldiers all the time and repair the damage done by the Protoss with the SCV. If they turn towards the workers, retreat them and resume the repairs. Place new Bunkers to the left of the Barracks, gradually decreasing the distance to the target Protoss structures. This way you might even destroy some of them while shooting from the Bunker. However once you have a bigger army at your disposal, attack with it. Deactivate the Cannon below by destroying the Pylon.
