StarCraft II "Maw Of The Void", BRUTAL. All achievements plus 10 year

Wiped the map and killed the Mothership in just over 55 minutes without losing any units in the "Rip Field" The last generator was taken out before the 47-minute mark.
A second command center would have saved time: mules to collect resources lying about, and scans to see what's coming, but it didn't occur to me.
