All In (Achievements) | Campaign - Final missions SC II: WoL Guide
Last update: 11 May 2016
All In:
The description says it all.
Turn and Burn:
During the final mission you'll be attacked by such an enormous amount of enemies, that you will get this achievement one way or another.
Aces High:
Things get complicated here, as you can use the artefact only once throughout the mission. The circumstances of the mission vary depending on your previous decisions. During All In you may be attacked by Zerg air forces or Nydus Worms.
In the first case the task is more difficult, as after some time you won't even know where to look. The Zergs will start incoming from everywhere. Their groups, forecasted by Matt, will eventually appear also at the back of the base and additionally you will be forced to constantly fight off the nasty Brood Lords.
You should focus your defence on Bunkers and Siege Tanks, but try to place Turrets around your base as soon as possible too. Begin producing Vikings and Banshees on a mass scale, which you will use to reduce the enemy's advantage in the air. Battlecruisers can also do, but they are very heavy and you will definitely feel it here.
With time, small airdrops will start landing in your base, they're not dangerous, but can pose a threat if not taken care of. What's worse, a might Leviathan will appear at around 70%. You might have had a taste of this best during Shatter the Sky (if you'd play through it, you'd be fighting Nydus Worms instead units produced by Spires). In the end, it will stop by your base and start morphing Mutalisks and attack if you come close.
Of course you won't have an easy task with the Nydus Worms as well, but in my humble opinion it's an easier way. Focus on producing Banshees - keep sending them to the Worms and replenish any losses. Don't forget about cloaking, through it won't always be as effective because of the many Overlords.
It's also good to have some resistant Battlecruisers as command. You can send them towards a Nydus Worms, which will certainly be appreciated by your units inside the Bunkers. Attack the Worms right after they appear, as otherwise you will fall into trouble. Try to avoid the groups of Hydralisks while attacking with Banshees. Of course make sure to build a network of Bunkers and as much properly placed (for example on cliffs) artillery as possible. The Worms will also appear inside your base.
Generally, you should start upgrading both fortifications by the road to the artefact hill. I'd suggest leaving your one shot until 90%, when the Zergs will start attacking like crazy. In the air force option, you can consider using it when the Leviathan appears. It won't kill him, but drain 1/3 of his life. As I mentioned in the main description, you will be also invaded by Kerrigan and around 40%, a fleet of Overlords will appear.
