Clear Sky Complete is a part of the Complete mod collection, which is a series of modifications created by professional artists dedicated to enhancing the S.T.A.L.K.E.R. games. The Complete mods focus on improving the original game’s graphics, sound, and atmosphere, while preserving its core elements. Built upon the success of STALKER Complete 2009 (which was downloaded well over 200,000 times), this entry in the Complete collection continues the tradition of aesthetically updating the game without changing the original story or gameplay. Fans can expect a polished and pure Zone experience designed around the most graphically demanding title of the S.T.A.L.K.E.R series - S.T.A.L.K.E.R. Clear Sky.
This mod fixes pretty much everything that was rushed about Clear Sky, save for the story. It makes it feel like an improved version of Shadow of Chernobyl, rather than the buggy disappointment that the original release was.
The only problem I've had is with my computer's 4650 HD ATI graphics card, whose suckyness has prevented me from completely finishing this game.
Excepting a lack of framerate on my end, the swamps and territories are really nice, every pixel of foilage and every gameplay element suggesting the words "Clear Sky" to the player, while still retaining (and recovering) everything that makes STALKER great.
