General information


Game information


The Sphere[1] 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.[2]
