Valve has announced that Portal 2 is now available worldwide. Mac gamers can sign in to Steam and download the game right now. Retailers are also preparing to sell the game as of today. The original Portal was named 2007's Game of the Year by no less than 30 publications across the world.

“Portal 2 is now available worldwide via Steam,” Valve said today. “Portal 2 draws from the award-winning formula of innovative gameplay, story, and music that earned the original Portal over 70 industry accolades and created a cult following.”

Building on the success of the original Portal, the sequel features not only a single-player game mode, but also a cooperative mode which features its own separate campaign with a unique story, test chambers, and two new player characters.

“Success will require them to not just act cooperatively, but to think cooperatively,” Valve said.

As for the single-player mode, it introduces new characters too, as well as fresh puzzle elements, and a much larger set of test chambers, something that will undoubtedly please those who believed the original Portal game was too short.

Portal 2 also boasts some advanced physics which allowed Valve to create a whole new range of challenges.

This resulted in a much larger but not harder game, the makers stress.

Last, but not least, Portal 2 will have what Valve calls “editing tools.” These will be made available separately, after launch, Valve said.
