This mod for the original STALKER Shadow of Chernobyl brings the game up to date with changes to the graphics, ai, sounds and bug fixes. The full list of features and download can be found at STALKER Complete 2009 mod for S.T.A.L.K.E.R.: Shadow of Chernobyl - Mod DB The graphics are a big improvement over the original and the game didn't crash at all as I played it through. (unlike the original which crashed frequently for me). A couple of additions I really liked where the sleeping bag and the tool box. The tool box is a one use item that allows you to repair guns or suits in the field. You'll need to patch the game to the latest version before using this mod. There's also a realistic weapon add-on on the download page. If you enjoy the STALKER games then I'd recommend getting this mod and playing it again.
