Video guide demonstrating how to beat the Starcraft 2 Wings of Liberty "Shatter the Sky" mission on Brutal mode while simultaneously unlocking the "Speed Too!" achievement. Note: Speed Too is unlocked by beating the mission on hard or brutal mode in under 25 minutes. The game time for the walkthrough you are about to see is 20 minutes and 2 seconds. This is a very easy mission to beat thanks to the Battlecruiser. There is very little anti-air on this map. The only real anti-air threat is the Leviathan, which can be defeated very easily by using mass Yamato Cannons. The trick to making this mission super easy is taking the expansion to the south of your base immediately with your starting Battlecruiser. Also, you should know that with just 3 Battlecruisers, you can clear out the center platform, the top center expansion, and the top left platform, clearing over half the map! This makes the Speed Too! achievement and this mission on Brutal mode quite easy.
