Automatic running

Implied:
* Walking

Contrast:
* Stamina

These may additionally have a sprint option which may occasionally make people think they're actually simply walking (at immense speed). For some reason many of these games include functionality for plain walking, but this is usually not default and no-one in multiplayer uses it and even in singleplayer this is mostly used as artificial difficulty increase.

Common in competitive multiplayer games, especially those with deathmatch style default mode.

Implies there's no stamina, but can coexist in cases where the auto run is actually auto jog and running is actually sprinting.
