This guide is for Feels Like the First Time
trophy which requires you to open a loot chest located on top of the bus stop within the Eastern area of the Arid Nexus - Badlands region.
Either fast travel there or grab this the first time you arrive there, walk up the stairs, hop on the little awning/shed, and then hop onto the roof.
There will be a loot chest on the roof, simply open it to nab the trophy.There is an optional quest that has you running around collection ECHO recordings of Handsome Jack. One of the recorders brings you on top of the bus stop, and the recorder is directly beside the loot chest. If you are having difficulty finding the building, simply do that quest to locate it.
