"Clear Sky's technological feature set is extremely impressive as well and the demo looked absolutely fabulous."

Также, игра "S.T.A.L.K.E.R.: Чистое Небо" стала одним из финалистов в "IGN's PC Best of E3 2008 Awards", номинация "Лучший шутер от первого лица".

"It's key to note that all three nominees for the best PC shooter of E3 have one thing in common: they are all essentially sandbox games that let you tackle a situation any way you want. That's a sign of just how far the FPS genre has evolved from its days of narrowly linear, highly-scripted gameplay."
