I’ve seen a couple of different examples on YouTube, but the theme is the same: a scary looking face (basically a large 2-D cutout) is chasing you and if it catches you you’re dead. A few questions:
Is this an application of the “Garry’s Mod” Half-Life 2 sandbox, or am I conflating two different things?
Does the face always know where you are, or can you lose it if you get out of sight and hide? Can it always get to you no matter where you are or do obstacles/ height differences thwart it? If there are weapons in the game can you fight it?
