In early 2000 an alpha build of S.T.A.L.K.E.R was released which generally looked stunning, however many of these features didn't make it into the final build, but the lost alpha mod aims to change all that. A mod that aims to revive an early version of the game teased prior to release, which included more, bigger areas, and other features that didn't make into Stalker: Shadow of Chernobyl. DeZ0wave announced today that stalker lost alpha has now been released. So now you can see for yourselves just how much has changed, and all the extra added features that DeZ0wave has implemented.
