Very rare1.4%ObjectiveOptionalSingle-player
Survive 3 minutes on at least a 3 star Wanted Level with all three characters together off mission.
Get all three characters together (a mission where they're grouped, or switch between them to gather them in free-roam) and survive 3 minutes at a 3-star wanted level or higher as a trio. Raise the stars with some chaos, then hunker down together and outlast the cops for three minutes.
