Dystopia, my favorite source mod, has just announced the release of version 1. New models, weapons, armor, and maps are just but the beginning of what to explore in the long awaited and now released version.
Fileplanet is hosting the file which you can grab here.
For those unfamiliar with Dystopia, it's a cyberpunk mod for Half-Life 2. When I say 'cyberpunk' I mean a world where corporations have taken over and the 'punks' (essentially the resistance) is fighting them back via means of computers and manpower. The game features a seamless transition from the real world to cyberspace unlike any other. I highly recommend checking this out.
