Trouble is brewing in this sleepy western spiral of the galaxy. It’s been five years since the alien infestation started – five years since The General, leader of the Gunmen, fell in battle driving back the silicon-based hordes and you took command.Gunman Chronicles is a story-driven first-person game powered by the Half-Life engine. Players take the role of a futuristic gunman with a mission to destroy the alien Xenomes that mysteriously began appearing five years earlier. Now it seems that someone has been altering the Xenomes’ DNA, allowing them to become bigger and stronger, plus they’ve somehow started spreading to planets across the western spiral arm of the galaxy. Game levels range from dinosaur-infested jungle ruins to techno wastelands. In order to rid the galaxy of the evil aliens, players can customize their weapons, control vehicles such as tanks, and be assisted by computer-controlled characters. There are also multiplayer game modes available for play over the Internet.
