GTA 5 Walkthrough: The Bureau Raid

In The Bureau Raid, Michael and Franklin infiltrate the FIB headquarters to delete incriminating data. There are two approaches.

Covert (roof entry): the crew enters from the top, and Franklin rappels down the elevator shaft to reach the servers while Michael provides cover — stealthier, but tense.

Fire Crew: the team enters through the front disguised as firefighters, then works its way up.

Either way it ends in a firefight and a getaway, so bring a capable gunman and keep your body armor topped up before you start. Pick the approach that suits how you like to play.
