You start in the southeastern part of the map. You have access to three zealots and three high templars. Go ahead and follow the instructions given by the game. Use the psionic storm when fighting the first group of enemies [1] and use feedback to get rid of spectre when fighting the second group [2]. Stand at the top of the stairs [3]. You will see Artanis and Kerrigan fighting a hybrid. Help them.

You gain control of the base [4] after the cutscene. Your objective is to destroy the void crystals [V1-V4] scattered across the map. Small groups of zerg attacking from the main base [5] will help you in this mission. The zerg have also four other smaller bases, but these ones will be destroyed by the enemies coming from the portal [6]. Among forces coming from the portal are too strong and the portal will generate a cloud on the conquered territories. After walking into the cloud your units will receive damage. Because of that, sending help to zerg is pointless, you better focus on destroying the void crystals.

Produce additional workers using the resources you have at the start. Gather the army and go west. Activate the first Xel'Naga vessel in point [X1]. You will find two others [X2][X3] while completing the main mission objective. You will also have a chance to collect some resource containers.

Produce another high templar and few zealots so that you have a total of 10 or more of them. If you want, you can combine four templars into two archons. Go with the whole army to destroy the first void crystal. You can choose from the [V1] standing on the sidelines or the [V2] attacked by zerg. The defenses of the target consist of few turrets, protoss or terran units and one hybrid. If needed, use Spear of Adun's abilities.

Focus on improving the base after destroying both crystals. You need more zealots and stalkers. Dark templars will come in handy as well. You will be attacked from time to time by the enemy, but similarly as during the previous missions the enemy will be a small threat to you. You will be warned about the attacks beforehand. If you want, you can set few photon cannons at the entrances to the base, but it is not mandatory.

Gather around 40 units of various type. It is a good idea to upgrade their weapon, armor and shields. Once you gathered the army, first attack the second Xel'Naga vessel [X2]. Then, together with zerg or alone, destroy the third void crystal [V3]. The base that protects it is only slightly stronger than the previous one, so you shouldn't have trouble with it. You should also have no trouble with small groups of enemies and fortifications scattered across the map. There is even a chance that you will not find them because first they will be destroyed by zerg.

Go east. Bypass the enemy bases [7][8]. They are too heavily guarded and you don't have time to get rid of them. Activate the last Xel'Naga vessel and then together with zerg attack the fourth void crystal [V4]. First you will find terran base and hybrids. Get through them. The crystal itself is protected by other hybrids, stronger than the ones you met previously. Destroy them and then focus your fire on the building.

Zerg must survive. It means that when the last void crystal is destroyed, at least one hive and some units must survive. If you don't care about achievements, you can wait and gather your forces at the price of zerg bases which will be destroyed by Amon. Amon needs around 25 minutes to destroy all zerg, so you can safely assume that you must complete the mission in less than around 24 minutes.
