GTA Online players can secure The Outcome of Endeavour in The Kortz Center Heist and the Panther Statue in The Cayo Perico Heist during The Heist Event, with a different condition attached to each target, according to the official announcement published on Steam.
The event also doubles first-time completion bonuses for several heists. Players can obtain The Great Circle Back, an artwork for a Mansion wall, by playing GTA Online through November 11.
How the guaranteed targets work
For the first Heist Event featuring The Kortz Center Heist, The Outcome of Endeavour is guaranteed. The artwork was previously reserved for players who reached Elitist status in the summer’s Fine Art Collector program, so the event offers another opportunity to obtain it.
In The Cayo Perico Heist, the Panther Statue is guaranteed on the first approach during the week of the announcement, which was published on November 6. The guarantee is tied to that first approach; the announcement does not give a precise end time.

First-time heist bonuses and Mansion artwork
During The Heist Event, first-time completion bonuses are doubled for the Original Heists, The Doomsday Heist and The Diamond Casino Heist. The increase applies to the first-time completion bonuses, rather than being described as a blanket increase to every heist payout.
The first completion of KnoWay Out pays twice as much GTA$ from November 5 to 11. That window also ends on the stated date for playing to obtain The Great Circle Back. The announcement does not specify how the Mansion artwork will be delivered.
More rewards from November 12 to December 2
From November 12 to December 2, all Contact Missions pay double GTA$ and RP. Rockstar names Madrazo’s Dispatch Services, Gerald’s Last Play, Premium Deluxe Repo Work and Lowriders among the eligible missions.
Over the same period, Freemode Challenges pay four times as much GTA$ and RP, while the Stunt Race Series pays triple GTA$ and RP to all participants. Those rewards give players several activities to choose from alongside the heist bonuses.
The announcement also lists double rewards for Sumo (Remix) and triple rewards for the Community Series, without specifying dates for those bonuses. The dated Contact Mission, challenge and race rewards have their own window, while the conditions for the 2 guaranteed heist targets remain separate.
