Frontline Nation is a turn-based strategy game situated in a near future Europe. Unprecedented war is upon us. Former alliances have withered and every nation is now on their own. Nationalism and militarism dominates the politics, which has allowed sinister leaders to take charge. Secretly they build their armies and make up plans how to annihilate their enemies.

Frontline Nation consists of two different gameplay levels, a strategic and a tactical. The strategic level is where the player manages production, diplomacy, research and coordination of military forces. The tactical level offers the player full control of its military units in a dynamically created hexagon-based battlefield. Form alliances with important nations, and honour them as long as they serve their purpose as you conspire to game control of over 45 countries.
