You are the leader of the Gunmen, the only few sources of law on the frontier. Five years ago the Xenome came, and the Gunmen only prevailed when the General sacrificed himself in a suicide attack.
The Xenome are back, bigger and deadlier than ever. Who is behind the Xenome infestation? Will you live long enough to find out?
Gunman Chronicles is a fully-fleshed out version of a Total Conversion what was for Quake, then Quake II, and finally Half-Life. It is a first-person shooter with lots of weapons and some rather creative level design and atmosphere.
Gunman Chronicles was originally a Half-Life modification named Gunman, and a Quake II total conversion before that, and a Quake total conversion before that. The game's designers hail from all over the world. Most of them have never met each other before, but they still managed to make the game.
German version
In the German version there are a number of changes:
All humans were replaced with robots
All blood was coloured green
Killed civilians don't die but sit on the ground
Steam
The game is usually a standalone installation, but can also be played via Steam with a downloadable patch, which is around 59 megs in size. You have to use and own a legitimate copy of the game, of course.
