Indoors

* Corridors
* Canyon

This also includes tunnels, subterranean setting, and anything else that severely limits view and movement distance in all directions (e.g. tight canyons) even city streets and backalleys if they're enough small.

This is commonly caused by engine's technical limitations or more rarely a conscious design choice outside technical thoughts.

Should not be used for sports, driving or simulation games unless it's unusual.

Should not be used if the game mixes both outdoor and indoor locations decently.
