The war is over. Mankind lost. Scattered and spread across the planet, the survivors search for refuge in the ruins of the old world. One of these stragglers stumbled across something that hasn't been seen by outside eyes for a long time...

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.

Featuring a large voice cast along with music from NxSG, Alphadeus and Egill And. Design, models and textures by Sam "SpAM_CAN" Morris, creator of the award winning map "Portal: Skyline"*, Portal 2 maps "Core Civ" and "Cave's Caves", and the GameSpot featured CS:Go map "Reclamation". Written by Sam Morris and Emilia Wennqvist, with sound design by Matt Turner.

This is "Volume One" of Outside Influence. Volume Two will be released at a later date as a mod for Portal 2, concluding the storyline started here. We are targeting release on Windows, Mac and Linux sometime soon.
