With a proper approach, this mission becomes very easy. Your objective is to destroy 12 null circuits. These objects are grouped in sets of three (marked on the map with letters A-D and numbers 2-4) and are assigned to one of four warehouses [A1-D1]. Each warehouse will open once proper null circuits are destroyed. After opening, a large group of protoss will appear on the map. They will destroy one of the zerg bases (2-5) and then leave the map. In other words, in order to complete the mission you must perform twelve precise attacks on marked objects. You must also defend the purifier core matrix [1] but it can be found next to your base, so both these locations can be protected at once.

So, how to complete this mission easily? Simply focus on aerial forces. Start with producing new workers. Quickly start gathering gas from all three sources and build 2 stargates. Later you can add one more. Construct all needed buildings and start producing void rays or carriers. Or both, if you don't want to use one-type army. Gather all your forces north from the core matrix, in the passage leading to the eastern part of your base. Thanks to that, you will be able to quickly react to enemies who will attack you from time to time. Gather about 10 ships and then move them west, destroying all null circuits [A2-A4] you can find there. Keep moving towards the buildings, destroying only units and fortifications which will give you some trouble. Just after destroying all three targets, allied units will appear on the map and take care of all zerg. All that's left for you is to gather all resource containers (if you have units that are able to do it).

On the west of the map you will also find the purifier warden [6]. It is a flying unit which has a very strong attack, large number of hit points and a group of supporting units which are healing it. In order to destroy it, you will need a large group of units able to destroy aerial targets, for example 10 carriers. Get close to the enemy, get rid of its backup and then concentrate your fire on the main target. Use Spear of Adun's abilities as well, they will prove to be very useful.

Get back to the base after getting rid of warden. Create new units and send the existing ones to defend. Upgrade the shields, weapon and armors to maximum, build also some turrets at the purifier core matrix because the enemy will send hybrids against it. You need 15 carriers to easily complete the mission. Once you gather the fleet, do the same as in case of first three null circuits and simply destroy them one after another. Each time the defenses will be stronger, but your large fleet should get through it with no bigger trouble. After destroying each set of three, retreat to the base to gather reinforcements and replenish the shields. Keep also attention to enemy attacks, they may force you to stop the attack.

If you don't want to use only the fleet which cannot gather resource containers, try mixed army. Let the colossus be the base of your army and support them with stalkers and zealots as living shields. Similarly as in case of fleets, don't worry about irrelevant units and buildings and concentrate on destroying the null circuits. The mission will end soon after you destroy the last one.
