Less than a week from today, everyone who pre-ordered will be playing the Left 4 Dead demo. We know! We can't believe it either. To make the wait easier, we've released the five minute movie that opens the game. Caution: The movie may actually make the wait harder. Anyway, happy Halloween.

Welcome to the Steam Community’s Offical Portal Game Group! We'll be using this space to announce upcoming Portal content and spotlight the growing pool of awesome Portal community contributions. To get us started, here's a slice of both:

As of today, Portal: Still Alive is available for download on Xbox LIVE! It features the entire original Portal game, as well as, new achievements and 14 bonus puzzles.

If you're short on cash, but still looking for new test chambers to solve, give these free Portal-like browser games a try.

Portal: The Flash Version
This polished 2D puzzle game is based directly on Portal's gameplay and setting. Its 40 levels use all of the familiar buttons, energy balls, and turrets. (And cake.)

Epsilon
Epsilon uses a set of interlinked portals in each Experimental Sciences Research Facility test course. Manipulate the portals with a simple point-and-click to guide the ball to the goal.

Shift
Shift 2
Shift 3
The Shift series contains some sly Portal references and uses a unique "shift" mechanic that is arguably even more mind-bending than portals. Pressing the shift key turns everything upside-down and inverts the world's solid and empty spaces. (Of course, spikes are always spikes.)

Fold
Fold's creator, Joel Esler, cites the Portal trailer as an inspiration for his gravity anomaly orbs. Think with gravity to overcome these sharp puzzles while avoiding sharp objects.

Hunted Forever
Hunted Forever includes several references to Portal, from the "Loading Portal Rip-off..." text in the beginning to the "neat gun" you make if you're "still alive" by the end. Run, jump, and climb to gather gears and hide from the ever-present death lasers and chainsaw drones.
