Half-Life 2

And we’re in for an incredibly enticing box all round, it seems. New shots of Portal and Team Fortress 2 have also been released, with both looking distinctive and wildly original. The striking style of the latter is said to be pushing Valve’s Source engine further than even Episode 2, giving you a whole new reason to re-subscribe to your Gold Live account. Portal, meanwhile, increasingly looks like a lot more than a simple puzzle game. Rather than dumping you in level after level, the dimension-bending puzzles are laid out in a logical, first-person-perspective building, where exploration takes you to each fresh challenge.
