In Cold Blood (achievements) | Kaldir missions SC II: HotS Guide
Last update: 11 May 2016
Harvest of Screams:
You receive this achievement automatically after the completion of the mission.
Ice Breaker:
Destroy 20 unfrozen enemy buildings. It is enough to launch attack on the Protos bases during flash freeze storms and destroy pylons and enemy forces only. Then, you need to wait for the storm to end to start destroying the remaining buildings.
Storm Chaser:
Complete the mission within 15 minutes on the normal difficulty level. It can be a bit tricky to try and get this achievement simultaneously with the Ice Breaker. It is best to save the game right before launching an attack on [4], and then, after you gain the achievement, load it again and go directly for the spire. In [5], you should ignore destroying the Protos fortifications and focus an the destruction of the main target only.
