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".

Hello Everyone!

I have been busy updating and revamping a lot of the older maps, and, I am now ready to showcase the full views of Testchamber 14 and Testchamber 16.

The updated chambers will be in the image gallery.

Testchamber 14:

I have made style changes to this chamber by removing the stairs leading up to the ball catcher


Removing the Observation Room where the Box Was Originally Seen

Testchamber 16:

This Chamber has had turrets being moved around and many lay out changes throughout the past week I've been working on it. (still prone to changing) I have also been working on metallic details for flooring and walls.

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

I remember starting mapping with this using freaking po_edit. I wanted to learn Hammer, but it took me about 2 months to find a tutorial which said that you pressed enter to create a brush. Everything before that just said "create the brush".

I never released my po_edit maps, because I knew they weren't up to a good standard. That didn't occur to some people, apparently.

Straightforward gameplay, and not too hard or too easy. Once you figure it out, its really fun.

Lowest Rated (3 agree) 5/10

what to say? this game is not challenging at all, completely boring and waaaay too short.

After 90 minutes of playing, just when i asked myself "when is this stupid tutorial over, i want puzzles!" the credits appeared and the game was over. it was really disappointing. the only thing that kept me from smashing my computer was this funny "still alive" song that was played in the credits.
that song is the only positive thing about this game. and certainly not worth 20 bucks.
