Trifecta Achievement in Halo: The Master Chief Collection

Like before, these predetermined Campaign playlists act as a means of experiencing a particular set missions that all share a common thread. Hand-crafted by the developer, some of these playlists are unique, such as all the vehicle-related missions. There's also playlists for Easy Campaign, Normal Campaign, Heroic Campaign, Legendary Campaign, and LASO Campaign.

Since the LASO Campaign playlist (Non Stop Action) must be completed for a separate achievement, all that is required is to complete a minimum of two other playlists for this achievement. In Halo 3: ODST, the two shortest playlists - which also prove to be quite enjoyable - are the following:

• Vehicle Rally - Uplift Reserve, Kizingo Boulevard, Kikowani Station
• Arena Battles - ONI Alpha Site, Coastal Highway

Simply pick and choose whichever three Campaign playlists you'd like to work on and once they have all been successfully completed, this achievement will be yours.
