Steel Horizon is a turn-based strategy game that can be played either as single player or head to head against an opponent. During your turn, you will have time to move your ships, assign battle groups, and attack nearby enemies. There are two different modes during gameplay, Strategy and Tactical.
During the Strategy Mode, you are allowed to move your ships and get them into position. You also have the ability to reassign ships to different groups and check on their status. After you have placed all of your ships the way you want them, and barring any actual combat, you end your turn and allow your opponent to do the same.
Tactical Mode is engaged whenever you enter combat. Combat itself is taken care of in real time. During battle, you target the enemy vessels and use whatever special tactics are provided to you by the ships in the group. Battles happen quickly and can be quite lopsided if you do not pay attention to what types of ships are going against one another. To simplify this, there is a paper, rocks, scissors relationship that you will have to insure sure you are not sending paper boats to battle against scissors.
You have the ability to upgrade your fleet. With each successful mission you complete in Single Player, you earn points that can be used at the end of the mission to upgrade with. There are 15 different ships that will be at your disposal.
There are Ports and Shipyards in the game that you will need to use to either produce the resources or build new ships. You will need to either claim the points of interest or take them over from the enemy. Taking over these ports is like any other capture the flag scenario. Park a ship outside the control square and hold it for a designated period of time.
