Embark on a grand adventure with the massive deep-sea expedition ship. Set sail with the LEGO City deep-sea expedition ship to recover the sunken treasure. A wreck full of gold bars has been discovered on the ocean floor. Board the fantastic expedition ship to rush to the site as quickly as possible. Onboard, you'll find the latest high-tech diving equipment. Send out the remote-controlled underwater vehicle and the dive scooter, then activate the winch system to lower the research submarine into the water. Next, climb into the shark cage and accompany the other divers to the ocean floor. Check out the amazing great white shark, the swordfish, and the octopus while you retrieve the gold bars from the sunken ship. But be careful: the wreck is quite unstable and could collapse at any moment.
