Smash and Grab (Achievements) | Campaign - Artifact missions SC II: WoL Guide
Last update: 11 May 2016
Smash and Grab:
Get to the Artifact, Destroy the Stone Zealots, Find Protoss Relics.
Rock Solid:
To even start thinking about succeeding, you have to move aside the Marines, as the Stone Zealots can kill them fairly easy. You'll have to use the most resistant unit you have, probably the newly-introduced in this mission Marauders.
Form a normal army at first (Marines) and take over the Protoss base. Afterwards form a group of at least a dozen Marauders aided with Medics. Having such a group, you will smash the Zealots without many losses.
Of course if you have a unit stronger than the Marauders, use it instead. One of the options is also building Bunkers nearby the Artifacts and stepping onto the marker afterwards.
Hit and Run:
I'd say you have around 10 minutes for preparations. It's not too much, so start building your economy from the very start and rely on both minerals and gas.
Organise yourself a nice Zerg defence and send a group of Marauders to clear the nearby bridge in the meantime. If you get attacked by the Protosses, you can always retreat to the base and have your bunkers take care of the pursuers.
Continuously keep on training new units, maybe with the exclusion of Firebats (if you have them), as they won't be able to show their full potential against the Protosses. Invest in the available mercenaries in the first part of the mission, so you can by more after the cooldown. Without them, attacking the Protoss base is very risky.
With a varied infantry and Medics, conduct the final invasion. Target especially the Pylons, which will deactivate the Cannons and factories producing new units. Don't destroy the whole base, focus on the essential buildings. Remember you have three Stone Zealots left to destroy.
Of course don't waste any time on collecting relics during this fifteen minutes long operation.
