The '''Sphere'''''Half-Life'' files is an unused alien creature from ''Half-Life''. It can be found in the game files.

It appears to be a small biological alien weapon inside an egg shaped black ball, which seems to act as a shell. When activated, the ball opens to reveal a turret-like organism shooting something out of its three red eyes, similar to the Vortigaunt. According to notes for an Alpha version, Vortigaunts were to have a device called "control sphere". This may be the official name of the sphere.Half-Life Alpha|''Half-Life'' Alpha (version .61) Notes (Half Life Main v6.doc) (August 26, 1998)
