Wake Up Buttercup Achievement in Halo: The Master Chief Collection

This achievement must be done on the Heroic difficulty (or higher).

After clearing about three to four waves of Covenant ships during the space battle in Long Night of Solace, you will be given a new objective: destroy the Corvette's engines and its escort. There isn't much strategy involved here other than making sure to stay alive, dodging incoming attacks from the Banshees and Seraphs, and focusing first on the Corvette's four engines. Once they are destroyed, you can then focus your attention on the escort ships, making sure to stay at a distance since the Corvette's turrets can still damage your Saber. Also, as added advice, although the game does mention it, use the Saber's machine gun to disable a Seraph's shields before opening fire on it with your missiles.
