What is "Fog Of War"?

Fog of War is a mechanic commonly used in strategy and tactical games where unexplored or unseen areas of the game map are obscured from the player's view. The term originates from military strategy, where the fog of war describes the uncertainty and lack of information about an opponent's movements and intentions on the battlefield. In video games, the Fog of War is employed to simulate this uncertainty, requiring players to explore and gather intelligence to uncover hidden areas and reveal potential threats.

For example, in real-time strategy games like "StarCraft," the Fog of War conceals parts of the map that players have not explored. As units move across the map, the shroud of the Fog of War is lifted, revealing the terrain and enemy units within the line of sight. This mechanic adds a layer of strategic depth, as players must carefully explore and maintain visibility to gather information about their opponents' actions, adapt their strategies, and plan effective attacks or defenses.

The Fog of War not only mirrors the unpredictability of real-world military situations but also introduces an element of suspense and strategic decision-making in gameplay. It encourages players to think critically, react to emerging threats, and devise informed strategies based on the incomplete information available. The mechanic enhances the overall challenge and immersion in strategy games, creating an environment where dynamic decision-making and adaptability are key to success.
