Heart of the Swarm Campaign: Kaldir Achievements- Shoot the Messenger

Normal Mode:

Shoot the Messenger (10): Complete the mission.  Such a dull achievement.

Warp in Peace (10): Destroy each shuttle that launches before it gets near enough to a conduit that it can begin warping.  This is slightly difficult thanks to the variety of flight paths the shuttles have, but obliterating docking bays quickly can really cut down on the difficulty here.  Make sure you have forces parked along the three main routes from docking bay to conduit so that you don't have to make any last minute rushes to avoid this achievement being broken.

Extreme Nexism (10): Destroy at least two Protoss nexi (nexuses?  Nexes?) during the mission.  This is actually pretty easy- you're likely going to wind up killing off at least this many just making sure you can collect the stasis chambers in relative peace (in many broken pieces is more like).  Just remember to actually bother going on the offensive and this one is yours.

Hard Mode:

My Cool Bay Explosions (10): Destroy all three launch bays.  This is a serious challenge, particularly if you came to Kaldir first and lack the melee support that aberrations and banelings can provide.  Particularly noteworthy given that accomplishing the necessary base assaults while both giving yourself enough time to reach the launch bays and still not allowing any shuttles to escape requires triply splitting your focus.  Those who aren’t as good at micromanagement are going to find this a very difficult challenge to face.  Taking maximum advantage of your ability to continuously produce both troops and spore colonies is pretty much essential to reaching this achievement, so be ready to use your minimap and unit group tabs to jump across the map on a frequent basis.  Keep Kerrigan on the offensive and continually supply her with troops and you can at least keep this one straightforwards, though.
