Portal 2 Intro Gameplay Video Surfaced; Darker, Creepier Than The First Game [Video]

Portal 2, the sequel to the wildly popular Portal, has been announced back in June and will be released in 2011. I can't wait for this game, absolutely enjoyed the puzzle solving in the first game. Few videos on the game have surfaced since June, but most of them were demos on the new features in the game.

Today, Valve has released an actual gameplay video to showcase the quality of the game. And also to tease eager gamers, like me. The video features the introduction scene of the game, a full 3 mins of gameplay. It seems like this time, the game is set in a darker tone with a more intense atmosphere, much creepier than the original. Watch the video in HD to get the best effect. ^.^
