World War II: Frontline Command is a World War II themed 3D RTS game built on the Steel Soldiers engine.
The game doesn't feature resource management; every mission starts with a fixed number of units with which you have to fulfill your mission. The fog of war in this game is a literal grey fog that shrouds the landscape. Only high objects such as buildings and treetops stick out through the fog. The fog disperses once you scout the terrain.
Available units include infantry, tanks and artillery. Your most important unit is the Commander. He has a much larger visibility range than any of the other units which allows him to spot targets from afar so that they can be attacked from a safe distance. Furthermore he boosts the morale of your units. Morale is affected by many factors such as separation, mission status and enemy fire. High morale improves the capabilities of your units, while low morale decreases their effectiveness. Besides the mist which disappears when in line of sight to show the terrain and possible enemy units, your units can also hear enemy units move when they are nearby.
The game features a campaign for both Axis and Allies and can be played in two difficulties: recruit and veteran. Besides a increase in difficulty, the veteran difficulty also features some changes in gameplay such as more dynamic missions, less health regeneration for your units and limited ammunition. Besides the campaign you can also play against others in online multiplayer.
