info_hint is a point entity available in all Source games.

Gives NPCs information about the world at this entity's location. It is the only NPC AI node that is not connected to the NPC navigation nodegraph, so NPCs will not move to info_hints, making them unsuitable for navigation hint_types such as "Crouch Cover Low"^[Clarify]. Non-navigation hint_types, like "World: Visually Interesting", or "World: Window", are more suitable.
