Barotrauma

Beneath the frozen surface of Europa, Jupiter’s moon, the ocean lies. Even Earth can’t compete with its size, mysteriousness, and riches. People have managed to drill the thick ice and dive straight into dark waters on a giant submarine.

Barotrauma’s general task is prosaic: dig minerals and gemstones to boost your underwater colony’s prosperity. Set up a strict military schedule and follow roles, so the crew’s mission works out trouble-free. Beware, the depths are haunted, and only teamwork gives you hope to survive. Unless one of your mates is a traitor.
