Grand Theft Auto V

This trophy is story-related and cannot be missed, it will unlock after completing the 57th story mission "The Bureau Raid".
This is the fifth heist mission. After finishing the preparations you can choose between two approaches for this mission. Following the "Fire Crew" option, you must go to the FIB building as Michael dressed as a janitor (which is automatically done for you). In between tedious mopping sections, you must plant incendiary bombs around the building. After that is done, go outside and detonate the bombs before going back in as a fireman (again, this will be automatic). Enter the building and take the hard drive, fight your way out then escape the cops and go back to Lester's house to finish this mission and unlock the trophy.
