Playdead Games has finally created a gameplay trailer of its upcoming XBLA game, Limbo. Although the game has been in development for four years, this is the first promotional effort from the studio comprised entirely of in-game footage -- albeit just a small glimpse of Limbo's haunting monochromatic world.

Don't be fooled by the seeming simplicity of the gameplay seen here. While Limbo is a platformer, it features many unique physics-based environmental puzzles, which aren't well demonstrated in this brief teaser. Also not featured in this video: some of the most scarring, gruesome death sequences we've ever seen in a game.
