The goal of Wolfzone mod is to make a single player freeplay with randomly generated quests/missions. No need to be a surrealistic simulation based on scarcity and pain, just something more fun and arcade style, an immersive walkabout into the zone.
Here is the early access version of the Wolfzone mod for Linux 64 bit. Keep in mind that it's a work in progress so don't expect too much at first.
