Choose upgrades for the problem stopping your next trip: vehicle depth, battery endurance, personal oxygen or base power. Vehicle modules, chassis and Biomod slots are separate systems.
First choice: prioritize depth when the destination exceeds your vehicle limit, endurance when energy cuts trips short, and oxygen equipment when the route requires a longer swim outside the vehicle.
Base modules
