How this system affects decisions
This rule affects map strategy. Read the entry’s stated mechanics together with its requirements and related unit or technology pages; its practical value depends on which parts of that system are active in the current match.
How to use this reference
Previously explored areas stay visible in muted form, but enemy movement and changes are hidden without current vision. Range, vision, and explored terrain answer different questions: attack range determines what a unit can hit, line of sight reveals nearby tiles, and fog rules determine what information remains visible to the player.
