Steel Diver

Campaign Despite the system's highly touted 3-D capabilities, Steel Diver actually plays in a side-scrolling perspective and in a 2-D plane, where the bulk of the depth is simply in background graphics.

Players control a submarine navigating underwater environments and a variety of hostile elements, including mines, enemy submarines, and various rocky obstacles.

Control is performed entirely through the touch-screen.

Players utilize horizontal and vertical sliders to move the sub forward horizontally and vertically in the water, and tilt a wheel to change the angle of the submarine.

The further the sliders are moved, the faster the speed.

Torpedoes and repairs, as well as adjusting the map screen are also used simply by tapping the appropriate points on the bottom screen.

Action isn't necessarily fast-paced, and players must learn to monitor and correct the movement of the submarine as it may continue to "drift" in the water.

Three different submarines are available at the start of each mission with different sizes and attributes, from small and fast to large and tough.

Periscope Strike Besides the regular campaign mode, played through the 2-D side scrolling environments, there is also a more 3-D style periscope mini-game segment.

All control is again performed through the touch-screen, with an option to rotate the view of the periscope by physically moving the 3DS system (and yourself in the process).

As this view is seen as if through a periscope, it takes on a first-person orientation.

Here, players again have the ability to dive and repair leaks, but must use some strategy to launch torpedoes at constantly moving distant ships.

Steel Commander This segment is a one or two-player turn-based strategy game played through an overhead hexagonal map, rather like the Battleship

Steel Diver for Nintendo 3DS is currently worth €15.83 loose, €5.70 complete in box, and €16.61 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Steel Diver has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Steel Diver, loose is €15.83 and CIB is €5.70 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Steel Diver is currently worth €15.83 loose, versus €12.38 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
