Hey, Axon1988: Quick question. Does LA play nice with the Steam version of Stalker? Or do I have to get a retail version from somewhere?

Well for now it's a completely stand alone game. Not sure what they are going to do for release. But from previous questions as far as I understand it, it works fine with steam.
As with all stalker mods you'll be adding a gamedata folder and editing some things. So Steam should be okay with that.
