All over the interweb, there are intermittent forum posts with a strange topic: how similar S.T.A.L.K.E.R. looks to Half Life 2 and Doom 3. These claims certainly do not go unfounded. Someone, with way too much free time, went through and manually compared the texture directories of Doom 3 and S.T.A.L.K.E.R. You'll see the results in the first two pictures below. A particular texture, lights_impflash.dds, has the exact same name of the Doom 3 version, excluding the extension. Half Life 2 has also been allegedly stolen from. Not only are the file names nearly identical (except for the extension), the images are extremely similar as well. Whether or not anything comes out of this depends on what ID Software and Valve decide to do. Do you think S.T.A.L.K.E.R textures are stolen?
