Many mini-maps make use of similar features. Common features are:
Fog of war In many games using a mini-map, the mini-map begins completely blank, while the map is automatically drawn as the player discovers new areas of the game world. After players discover new areas, the terrain of the discovered area often remains visible on the mini-map. If the player's characters or units cease to see the area, the area might be covered by a
fog of war, so that unit or structure movements in that area will not be shown. Things in a fog of war portion of a mini-map may not be updated until they are rediscovered.
Layers Similar to custom layers in
Google Earth, some team-oriented multiplayer games, such as
Age of Empires II or
Empire Earth, allow players to draw temporary lines, signals or markings on the mini-map for others to see. This allows for quick communication over large distances in games.
Rotation and zoom In some 3D video games, the mini-map rotates when the player character or game camera faces different directions to keep the top of the map always corresponding to forward from the camera's point of view. This is common for games in the
Grand Theft Auto series, and many racing games that show the track in a mini-map. In other games such as
The Legend of Zelda series, the map does not rotate but features an arrow that moves about and rotates to show the player character's position and the direction they're facing. In some games, mini-maps that only show the close surrounding area often have icons on the edge to show the direction of locations or characters outside the area shown on the map. Some games also have a feature where the mini-map zooms out when the player character is travelling at high speed and zooms back in when they slow down. ==Automap==
