The Crucible (achievements) | Zerus missions SC II: HotS Guide
Last update: 11 May 2016
The Crucible:
This achievement is awarded automatically after the completion of the mission.
Epic Meal:
Kill 75 enemy units by creating the primal locust. It is enough to call for the reinforcements each time a larger primal zerg group approaches your base.
Can't touch this Chrysalis:
The Kerrigan Chrysalis cant' take any damage while you are playing at the normal difficulty level. What's useful to achieve this is mutalisks that protect the queen from aerial attacks, and block the passage [4]. I recommend that you save your game every several minutes and pay special attention to primal zerg airborne units. Especially throughout the last five minutes of the game, when they will launch a massive attack on your base.
