Former European-only publisher Deep Silver has announced that it will be publishing the North American edition of S.T.A.L.K.E.R.: Clear Sky (PC).

Though developer GSC Game World revealed long ago that its survival FPS prequel would hit retailers and Steam on August 29, no North American publisher was listed at the time.

Owned by larger publisher Koch Media, Deep Silver expanded its operations to include North American publishing less than a week ago.

New at FileShack is a trailer from developer GSC Game World showing off some of the DirectX 10 effects in the upcoming survival FPS-RPG S.T.A.L.K.E.R.: Clear Sky (PC).

Included in the demonstration are glimpses of god rays, soft water, volumetric fire, dynamic wet surfaces, water splashes, and more.
