Mission 15 - Unsealing the Past | Achievements - Legacy of the Void SC II: Legacy of the Void Guide
Last update: 11 May 2016
Unsealing the Past. Requires you to complete the mission on any difficulty level.
Pest Control. Bury the entrances to zerg caves sooner than 40 seconds after zerg will start crawling from it. In other words, you must bury the caves in points [6] and [7] just after you find them.
Brood War. Destroy all zerg buildings while playing on normal difficulty level. Very easy, you must simply destroy all buildings on megalith's path. Aerial units supported by colossus will be perfect for the job. You must only remember about the enemy base in point [4] and about enemy buildings near the two power core housings [C1][C2]. Both these places can be cleared of enemies while the megalith will be working on the next stasis locks.
Termination Protocols. Destroy all zerg lairs before the megalith will reach the fourth stasis lock on hard difficulty level. This achievement requires you to destroy two buildings in point [4] and one building per each point [7-10]. The only trouble is that you must simultaneously control two armies. The first will be destroying the lairs while the second one will protect the megalith. In addition to that, you must act partially against the mission objective, allowing the enemies to attack the megalith. The megalith is slow and to attack it must stop in one place. It also regenerates health after visiting each stasis lock. So, it is profitable for you when it is fighting the zerg attacking it, as each such battle gives you few additional seconds for obtaining the achievement.
Start the mission with building the second assimilator and stargate. Construct destroyers as soon as you can. Use the forces you have at the start to help megalith reach the first stasis lock [2]. Gather destroyers at the entrances to the base so that they will serve as its protection. Just when you gather around 5 of them, send them south to point [4] and destroy both lairs. During this time the megalith should move to the second stasis lock [3], so protect it during the journey. Keep producing the destroyers, you can also create the second stargate. Upgrade the weapon and armor of flying units. Create few stalkers as well and send them to the megalith. It would be good if three starting colossuses would still be available.
When the megalith will start leaving the second stasis lock you should have more than 10 destroyers. Send them north, to the lairs [8-10]. Destroy them starting with the eastern one. In case of trouble, help yourself with abilities. At the same time colossus and stalkers are tasked with protecting the megalith. Destroy the turrets, ultralisks and all other resistant targets with which the megalith can have biggest trouble. Leave the smaller units alone, they will only slow down the unit you are defending. You must be very careful as the megalith is a fragile unit and it will be quickly destroyed if attacked from all sides at once.
When the megalith will reach the third stasis lock [5], all three lairs on the north should be destroyed. Add the destroyers to the main army protecting the megalith. Wait for the unit to go north, to the fourth stasis lock [7] and provide it with protection. This part of the mission is similar to the "regular" version, but with one difference - when you will be near the fourth stasis lock, you must quickly destroy the last lair, even if the megalith will be seriously hurt then. The journey to the fifth one will be easy.
All that time you must remember about defending the base. The destroyers are using many resources, you should also have a large stock of minerals. Create many zealots and photon cannons supported by shield batteries for protecting the eastern entrance, as you will be attacked only there during the later part of the mission.
