The briefing
Published 12 December 2019. This archival report describes the announcement and offers of that period; temporary rewards do not remain active indefinitely.
The Diamond Casino Heist launched on December 12, 2019 with Lester and the Cheng family organizing a robbery against the casino’s new owners. An Arcade provided the planning base, combining a public-facing business with the preparations for an underground operation.
The launch also added vehicles, iFruit Radio, signal-jammer targets and a separate killer-clue investigation. Those activities connect to the update but have different rewards and unlocks; completing one does not automatically finish the heist’s reconnaissance or preparations. The heist’s multiple approaches made planning a recurring choice rather than simply replaying an identical route. Read the release report alongside the job guide to distinguish the narrative introduction, required property and optional new collectibles.
