When a trailer for an upcoming game shows no real gameplay features but still blows us away with just the game engine features, it has to be something special. Such is the case with the new "atmospheric" trailer for S.T.A.L.K.E.R. Clear Sky, the upcoming prequel to GSC Game World's 2007 first person shooter.

The over 5 minute trailer can be downloaded over at Big Download and shows off a number of the game's new visual effects compared to the original S.T.A.L.K.E.R. game including more bump detail on the level textures, volumetric light sources, better rain and wet ground effects and even better character details. The game, to be published by Deep Silver, is scheduled to be released in late August.
