On June 14th, Valve News Network released a video discussing Steam Direct, Valve's game submission system that has replaced Steam Greenlight.

The video seemed to use footage from a Portal 1 mod, as I didn't recognise any of the levels from the original Portal. I'd love to try the mod, but neither the description nor comments shed any light on the mod's name.

Here is a screenshot taken from the video:

Modded Portal Level

I've already ruled out Portal: Prelude, Blue Portals, Portal Pro, Portal: The Flash Version Mappack, and Portal: Unity.

    What makes you suspect a mod is even being used? The level layout? To me, it looks like normal Portal gameplay.

    @TimmyJim The level layouts are different. I didn't recognise any of them from the original Portal. Turns out it was from Aperture Dèjá vu.

    @TimmyJim - It doesn't look like any Portal level I've seen

Apparently the footage is from Aperture Dèjá vu; a mod for Portal 1 released in 2009.

[Aperture Dèjá vu] is a non-linear map which have many paths to take and reach the end. The point is, that you play a map one time and you are happy. Then you have a little break in Portal, because there aren't any new released maps for some time. But the answer is here: play the Deja-Vu again, but choose a different path with different puzzles. You can choose freely the way that is going to lead you to the end.

You can see the name of the mod shown on the Portal Gun itself.
