Didn't Like This Ship Anyways
From Halopedia, the Halo wiki
Didn't Like This Ship Anyways is an achievement in Halo: The Master Chief Collection. It is unlocked by beating the 15 minute par time on The Pillar of Autumn. The achievement is worth 10 Gamerscore and can be unlocked on any difficulty.
As a general rule, it is easier to complete par time achievements on easier difficulties. For this achievement however, players may wish to attempt the run on Heroic as this allows the player to skip the tutorial in the Cryo Bay.
