Unattainable: after patch 1.05 the Death Runs 'Craggy Crew' and 'Buckle Down' can no longer be started. To receive this trophy you'll need to re-install the game (without installing the patch) and start a new playthrough (as the 1.05 save is not compatible with the 1.00 version of the game).

There are a total of 16 archangels that can be built for the Mangum Opus, which you must win a race in legendary time with each Archangel for this trophy. The required time for each race can be depicted during the vehicle selection screen, on the right where the times are depicted (the Token time depicts the legendary time that must be beaten). Once you have won a race in legendary time with each Archangel, the trophy will unlock. Refer to the video depicted under  Running Wild.

Note: Archangels must be built before using them first. To build the required Archangel, go to the garage tab in the pause menu and press . All parts of an Archangel must be bought to enter the specific Death Run.
