segafreak writes "ShackNews reports that S.T.A.L.K.E.R.:Shadow of Chernobyl may contain unlicensed assets from other commercial games such as Doom 3 and Half Life 2. Though this has yet to be confirmed by any of the developers involved, if true this would be somewhat worrying. 'Responding to inquiries made by Shacknews, id Software CEO Todd Hollshead stated: I've seen a post on a web forum that claims DOOM3 assets are used in another game, but we've been working hard on Enemy Territory: Quake Wars as well as our own internal project and have not had the time to fully investigate or otherwise verify that the claim is true. Only from what I've seen on the Web, it's concerning. However, it may turn out to be nothing.'"
