Delay Announcement
  • LOD'ed projected textures
  • Spacially corrected reflections (parallax correction)
  • Video textures
  • Enhanced refraction shading
  • Reworked user interface
  • Basic support for the VPK2 format
  • Full particle editor support
  • An improved version of the Hammer editor
  • A new SDK launcher with support for workshop uploads and launching of user-defined tools.

We've been completely revamping the art style and working from uncompressed assets, as well as redesigning various models to match the new look. We've also refocused the gameplay from what we once had to something new and innovative that expands the Portal formula in a major way. I don't want to say more right now (we're planning a media release sometime soon), but rest assured that Outside Influence will be far better for the delay.

TL;DR: The game will be released and has not been cancelled, but won't be launching this month.

Release date: Late 2017-Early 2018
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...

NOTE: Is a third-party mod, not endorsed or created by Valve.

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, improved visuals 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 prize 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 Wake, 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.

(*Due to Greenlight restrictions, I can't directly link Portal: Skyline here. You can find it either on our website, or via your search engine of choice.)

Thanks for updating the thread, and for not giving up! We're all here supporting you even if we sound a little impatient :D
We'll all be looking forward to eventual release as this is probably one of the only Portal / Portal 2 mods that is Still Alive to this day.

Hi! I'm aware that at this point, it's been literal years since I posted a public update here. Just want to say that I'm still working, but it's basically just me, and I have a full time job and other life commitments to manage. It's still coming, just... when it's ready.
