Portal has been called one of the most innovative games of the decade. A hybrid of FPS style and a new genre of spatial brain teasers, Portal offers hours of totally unique gameplay.

Set in the mysterious Aperture Science Laboratories, players must solve physical puzzles and challenges by opening portals, maneuvering objects, and moving themselves through space in ways that used to be impossible.

Playing Portal today will teach you how to love a "companion cube", whether a computer named GLaDOS really wants you dead, and why your friends keep telling you "the cake is a lie".

Progress so far. Plus demo?


Edit: Maps have been released. Check on the Combine Occupation mod page.

Hey there.

This is my first public mod release, and so, I'm trying to stay consistent with it. For the past few days, I have been working to make the first two maps as enjoyable as possible (these are the maps I intend to package with the demo). And, so far, I like them. However, I would like the opinion of the majority.

On 9/27, I'll be releasing the current state of the first two maps. If I recieve good feedback, I'll push on with the rest of the maps, and tidy up with some fixes right before the full mod releases. If I don't, I'll improve on it until people like it. Signing off, Qloak.

Looks like some mods need indivual fixes to run with the SteamPipe version
