Easy way to get this achievement. You have to beat an insane computer in less than 5 minutes. Both you and your opponent must be zerg.
-Go 6 pool.
-When the spawning pool is halfway done, send two drones to the enemy’s base.
-Build 2 spine crawlers behind his mineral line, in a way the drones won’t be able to surround them.
Once the spines are ready and start attacking the drones, the computer will GG.
