Swim through the water tanker

Swim through the water tanker was a mission in Ratchet & Clank. Ratchet and Clank explored the water tanker of Drek's fleet and found a CodeBot.

Walkthrough
Jump into the pool of water inside the launch bay and use the Hydro-Pack to activate three rings to open a locked gate. In the next room you will find a set-up similar to the mission "Explore the coolant system". Push the button to disable the electricity for eighty seconds and begin to swim through the tunnel. Many Spiderbot-like robots with lasers, rotating fans of some sort of energy field and mines litter and clutter this tunnel. The timer is slightly generous, as you can complete the mission with around 15 to 25 seconds to spare. Once you have to swim through another set of rings you will have reached the end. A transport shuttle will take you back to the launch bay.
