The Dig (Achievements) | Campaign - Artifact missions SC II: WoL Guide

Last update: 11 May 2016

The Dig:

Recover the Laser Drill, Destroy the Xel'Naga Temple, The Laser Drill Must Survive, Find Protoss Relics.

Drill Hard:

You will complete this by simply playing through the mission. At some point, Matt will let you control the Laser manually, so you can use it to destroy the more dangerous enemies (like Archons or Colossuses). You must do it to simply survive and you will hit 20 victims quite fast.

The Achievement doesn't require you to complete the mission.

Yippee-Ki-Yay:

In order to be able to shoot the enemy buildings, you have to first of all see them. The snag is that the Protoss buildings are on hills. You don't need (even can't, as you wouldn't have time for it) form squads and send them there. Instead, use the Drill, which however has to know where to shoot.

Airborne units would be useful for pointing the Laser at the buildings, though I doubt you have any. Instead, you can use... a building, like the Command Center which I'd suggest (build a second one). The structure is quite resistant and can survive many attacks. Move once you're sure your base is protected enough with Bunkers and Tanks.

I'd suggest packing a few SCVs onto the Center, which will be able to repair the building in case it gets damaged badly. Afterwards they can return onboard and you will be able to continue discovering the area.

Use the Laser to destroy anything that can damage the building, which includes Photon Cannons, Void Rays and Stalkers. Take out the buildings afterwards. I'd suggest targeting the main, northern base, as the Probes there will be very persistent about repairing any damage dealt to the buildings, unlike the one in the east.

Queuing actions comes in handy here. You can mark a series of targets for the Laser by holding down Shift. While you're destroying the enemy buildings, keep on checking the minimap for any incoming Archons or Colossuses.

The achievement is rewarded during the mission.
