Hello Test subjects!

A new portal mod has popped onto Steam Greenlight this week: "Portal: Outside Influence".

Outside Influence is a mod for the original Portal; a new story set within the shared Half-Life/Portal universe, with new testing elements, environments and music. Contains additional features, such as fully voiced audio logs that tell the stories of those who worked at Aperture Science in its last days, a togglable hint system and a zoom scope a la Portal 2.
