Line of sight
Units and buildings reveal nearby terrain and enemies within their vision, while unexplored areas remain hidden.

Overview
Units and buildings reveal nearby terrain and enemies within their vision, while unexplored areas remain hidden.
How this system affects decisions
Information and access are strategic resources: scouting reveals where to defend or attack, while terrain and line of sight affect which routes and targets can be reached safely. Use the mechanic together with the map layout rather than treating it as an isolated statistic.
How to use this reference
Units and buildings reveal nearby terrain and enemies within their vision, while unexplored areas remain hidden. 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.
