Portal

Valve software, creators of the Half-Life series, has released a video of their upcoming game Portal. If you've played 3DRealms title, Prey, you've already experienced the portal. Running through the portal warps your player to another location. Valve takes the portal concept one step further by equipping the player with a portal gun. Fire the gun once and you create the exit. Firing a second time creates the entrance. Sounds simple, right? Check out some of the levels previewed in the clip below. It's also been reported that Half-Life 2 is coming to the 360 and will be bundled Episode 1, 2, Team Fortress 2 and Portal...woohoo!
