Lester informs the player that they can steal some explosives from some underwater wreckage where salvage crews keep their stash. This can be in places such as the Sonar Collections Dock in Paleto Cove or in Banning. However, when they get there, Merryweather agents are already stationed there, whom the player must avoid or they will become hostile.
The player must dive underwater to collect the two explosives, which are white boxes with orange lights, and bring them back to the Arcade. a scuba suit is provided nearby to help the player breathe underwater while searching for them. When both explosives are delivered, the mission is complete.
