Steel Diver was originally a tech demo for Nintendo DS; it has since been redeveloped for Nintendo 3DS. Steel Diver is a 3D action game in which the player takes control of a submarine and guides it through three different types of stages: Missions, in which the player navigates an obstacle course and must get the submarine to complete certain objectives; Periscope Strike, in which the player uses the motion sensors of the Nintendo 3DS to locate enemy ships and sink them; and Steel Commander, where the player must use strategy to locate enemy ships and try to sink them.

The game uses the Touch Screen in novel ways for each mode; there is simulation of the inside of a submarine with levers and switches to control the vessel for Mission and Periscope Strike modes.

The player can also share the game with another by using Download Play; this opens up Steel Commander into a 2-Player experience.

Steel Diver is an action-packed submarine combat game from Nintendo that immerses players in amazing 3D environments. Branching paths, split-second decisions and attacks from enemy ships make for a thrilling undersea adventure. The mix of 3D game play and one-of-a-kind controlsusing the gyroscope and touch screen of the Nintendo 3DS systemmakes for an unique combination that must be experienced to be believed.
