Protoss Mission 10: Eye of the Storm (final mission) - StarCraft Walkthrough / Speedrun

The Zerg base is heavily protected, especially their aggressive queens and defilers can be very annoying for most army types. You can nuke the Overmind with ghosts, but it's not a reliable strategy due to all of the overlord patrols.
To no surprise, mass carriers are once again the easiest strategy. The biggest threat are the Zerg's defiler's plague spell, which brings them all the way down to 1 HP. I bring along some observers to try to spot the burrowed defilers, but I get hit nonetheless. Just make sure to go all the way to the population limit and you should be able to power through.
