Boat Simulator 2 is a brand new game where you can learn how to drive 4 types of water vehicles including Submarine. Also, 2 amazing landscapes are waiting for you. Have fun! WASD/Arrows - drive, V - change boat, C - change camera, RMB - move camera, Wheel MB - Zoom In/Out, H/J - hide control instruction / hide control sliders. For Submarine, there is a Slider to control depth. You could drive a simulate boat that maybe you will never drive. How amazing!
