The "Nightlife Leak" is a key mission within GTA Online’s The Contract DLC, centered around recovering stolen music belonging to Dr. Dre. It is a multi-part VIP contract that involves stealth, combat, and chase sequences, offering players a cinematic and action-packed experience.

The mission begins after completing preliminary tasks called The Nightclub and The Marina missions. Once these are done, players return to their Agency and accept the Nightlife Leak contract to start the final phase.

Players head to the Casino Garage and take an elevator to the penthouse level.Inside the penthouse, players locate a promoter playing unreleased music on turntables in room 520. The goal is to steal a laptop containing the stolen tracks by pressing right on the D-pad.Upon stealing the laptop, the promoter flees, triggering a firefight with multiple guards. Players must take cover and eliminate enemies while chasing the promoter through the penthouse corridors.

After clearing the guards, players descend to the club floor, continuing the firefight before finally securing a backpack from the promoter.The mission concludes by escaping to the Casino Garage, evading enemy gunfire, and returning the stolen music to the Agency.

Players have the option to approach parts of the mission stealthily, especially in the initial infiltration of the nightclub, where donning a cleaning uniform and using a cleaning van can help avoid suspicion. However, the mission often escalates into intense firefights, requiring quick weapon swaps and tactical cover use.
