Emergency Shutdown

Emergency Shutdown is an achievement in Halo: The Master Chief Collection. This achievement is obtained when a player beats the par score of 25,000 points on the level Shutdown.

Tips
Turn on the Tough Luck and Thunderstorm skulls on Legendary. Switch the Pelican's weapon to the Spartan Laser and destroy all of the Phantoms and Banshees outside one of the towers; the Laser's firing range is just outside the firing range of Phantoms. Once all the Covenant vehicles are destroyed, head to the final tower and rush to the end of the level to take advantage of the time multiplier.
