Mission 8 - Brothers in Arms | Achievements - Legacy of the Void SC II: Legacy of the Void Guide
Last update: 11 May 2016
Brothers in Arms. Requires you to complete the mission on any difficulty level.
Mental Breakdown. Destroy 80 or more enemy units during the stun caused by keystone. A very simple task. Don't help your allies in their battle with enemy terran. Instead, improve your army. When you will be reaching the end of time, gather the army in a place that will be attacked by hybrids. However, don't stand in one place but start the attack. Destroy enemy units until the hybrid appears nearby. Focus on it, destroy it and get back to killing the enemies until another hybrid will appear. Repeat every time when the keystone will be active. What makes this easier is the fact that after killing all hybrids you will always have few seconds of peace during which you can focus on destroying enemy units and buildings. Due to the necessity of attacking only during specific moments, the operation might make the mission time much longer.
For the Alliance. Don't let your allies lose more than 5 buildings on normal difficulty level. A very easy task. All you need to do is not let hybrids get near the bases of your allies [3-6]. This includes the frontline bases as well, as the game counts all allied buildings, no matter where they were built and what are they. Your allies are able to easily fight enemy terran and not allow their bases to be attacked, but they are helpless against hybrids. At least on normal difficulty level, because on higher ones your help will be needed also in battles with terran. They will send large attacks which from time to time will be able to destroy some allied build, like for example a bunker. So, if you have cleaned one of the places for the ally to build the outpost, wait for him to build the bunkers and position his siege tanks. Thanks to that the chance for him to lose a building during enemy attack will drop rapidly.
Disruptor Junction. Destroy 55 enemy buildings while the Keystone is active on high difficulty level. Use the same tactic as with Mental Breakdown, but this time on buildings. A larger number of hybrids make the job harder, at the beginning killing them will take you more time than destroying the enemy buildings. However, further in the mission this should change. At least until you attack further enemy positions, where you will find single hybrids as well. Kill them before you start destroying buildings. You should also wait with attacking the main enemy base [7-9] until the keystone is active. Once the activation happens, quickly get rid of all hybrids and destroy as many buildings as you can. Once it is done, retreat and wait for another activation of the artifact.
