Any dive with an optional secondary objective displayed on the HUD
A secondary objective shown on the HUD can add Gold and experience to a run. The efficient approach is to collect or defeat the required targets while following the main route, then confirm the objective is complete before triggering extraction. This is a repeatable activity across dives where a secondary goal is available, though the exact task depends on the mission. Use the Gold on useful mid-dive options or let any unused amount convert to XP after the run.
