Submerge yourself into this watery world by taking the controls of your very own submarine, guiding it safely past obstacles and dodging attacks from enemy ships out to get you. Enjoy three different game modes in Steel Diver, each offering varied and fun submarine action in full glasses-free 3D. In the Mission mode, you must carefully navigate an aquatic obstacle course, completing objectives whilst being sure to avoid dangerous obstacles and persistent enemies; whereas in Periscope Strike you must use the Nintendo 3DS gyro sensor to locate and sink encroaching enemy ships. Try spinning around in a chair and watching the 3D sea horizon move with you – it really is like looking through a submarine periscope, although watch out for the battle ship in the horizon!
