Steel Horizon is a turn-based strategy game developed by British studio Climax Group and published by Konami for the Sony PlayStation Portable and Nintendo DS. It was released in March 2007 in the United States for the Nintendo DS, with a later release for the PlayStation Portable in July 2007.
The game takes place at sea, during World War II, where the player, an American captain, commands allied forces against the axis forces. The game also features a multiplayer mode where players can battle rival players.
There are several different playable ships. These include battleships, aircraft carriers, submarines, destroyers, battlecruisers, cruisers, PT boats, repair ships, cargo ships, landing craft and minelayers. Every ship has a special move that can be triggered during tactical battle. Aircraft carriers can use ace pilot. In the beginning the player must choose between 3 different types of upgradeable ships, a destroyer, a battleship, and a submarine. The enemies do not vary if the player chose any of them. They are standard linear enemies.
