Supernova (Achievements) | Campaign - Artifact missions SC II: WoL Guide
Last update: 11 May 2016
Supernova:
Clear the Landing Zone, Destroy the Artifact Vault, Find 4 Protoss Relics.
Cool Running:
I can't imagine you leaving any units behind to burn in the fire, well, unless you completely forget about of them while moving your base. Contrary to some opinions, the buildings (including side-buildings) don't need to be saved - it's just about the units.
Shock and Awe:
Start training as much Banshees as you can from the very beginning, completely forgetting about any other types (or just make some for the sake of defending your base). I'd suggest moving the beginning infantry to a Bunker, as they stand no chance against the mighty Protosses. Remember that the counter increases only when your Banshees are cloaked, which you can overlook in the heat of the battle.
Keep increasing your fleet, while fighting off the increasingly difficult Tal'darim attacks. Between the attacks, you can head deeper into the map and eliminate enemy groups, for example by the relics. If you want you can also check the north-west part of the map, with one of the Protoss bases. However try to defend your own base above all, as it will also bring additional victims onto your account.
Wherever you go, eliminate the Photon Cannons (detection) or the Pylons which are powering them in the first place. Without them around you will be safe and the numerous Stalkers and Sentries won't be able to see you. The Protosses are almost sure not to use any other detection methods. Also keep an eye on the Banshees' energy, as they can't stay invisible forever.
As you probably know, you will have to run away after some time and settle in the Protoss base indicated by Matt. Of course use the Banshees. Firstly be sure to destroy everything that can harm you in case you run out of energy. Afterwards eliminate the Nexus, Pylons (the base will cease to produce units), the Probes and only afterwards the other, defenceless Zealots and Colossuses. That way you will provide the others with a safe passage.
Afterwards systematically raid the other enemy bases. I think you won't have to move for the second time and you'll complete the Achievement before the fire gets you. You don't need to complete the whole mission.
