Steel Horizon review at NintendoWorldReport.

"Strategy games are supposed to pit you and opponent against each other, with each side attempting to outwit and outmaneuver the other to gain a tactical advantage. Steel Horizon takes the genre template and adds modern naval warfare. The resulting DS game has multiple problems that turns the mental battle against the computer into a physical battle against the game's design and interface.

Steel Horizon is a turn-based game with a sprinkling of real-time combat. You have a variety of ships to build up your fleet from mission to mission, including battleships, submarines, aircraft carriers, destroyers, cruisers and more. Ships can be grouped in any combination of units to increase that group's firepower, but if the group includes a slower ship, that group's movement will be restricted. Position and movement are based on a traditional grid system, and to engage in combat one must simply get close to an enemy group and attack."
