• Three Heist-themed clothing items with a Special Outfit type, two Cops and Crooks-themed masks, five new hairstyles, two new contact lenses, and four new audio files relating to the Heist missions. The audio files were identified as an alarm bell, the sound of a vault opening, sirens, and a background track.
• A new phone contact named Jeff will be featured, which will give players a chance to resurrect a killed crew member during a Heist mission.
• An e-mail option will be available for last generation players. This feature will let you send an e-mail to your fellow crew members. Whoever sends the e-mail will be the Heist mission's leader. All players will be able to use their Heist planning board to select a location, a role for the crew members, and the "length of time before the Heist request expires from their 'E-mail' app on their phone," according to Gamepur.
• The Heists update will feature a country bank heist, where players can rob a rural bank while wearing ballistic armor. There is also a mission that involves stealing artifacts from the military base. The mission's description is: "Vikings gang members have to steal an artifact from the military base while cops are required to secure the item and bring it back to the army base." An ornate bank heist is also included.
