Trouble is brewing in this sleepy western spiral of the galaxy. It's been five years since the infestation of the alien Xenomes started - five years since The General, leader of the Gunmen, fell in battle leaving you to take command. Now, a mysterious presence has tinkered with the DNA of these Xenomes, making them bigger and stronger than before, and the scourge is spreading once again. As leader of the Gunman, the only law in this area of the galaxy, you must set things right. Find the source of this hostile invasion, and clear these alien scum from the rim or the galaxy!

Gunman Chronicles combines a wild-west sensibility with high-tech styling to create a thrilling and visually unique first-person action experience - powered by the Half-Life engine! All of the amazing effects and frighteningly realistic AI that made Half-Life the undisputed king of first-person action have been brought to Gunman Chronicles, a tale of revenge and redemption on the rim of the galaxy.

Gunman Chronicle's massive single-player campaign takes you through unique and dangerous worlds including dinosaur-infested jungle ruins and awesome techno-wastelands. But fear not! As a Gunman, you will not travel unarmed. An arsenal of high-tech customizable weaponry will be at your disposal to fight off the evil that you find. Controllable vehicles such as tanks and friendly computer-controlled characters will also aid you in your cause.

Aside from the challenge of the single-player game, you can battle online with a variety of multiplayer modes that take advantage of the Half-Life engine's ease-of-use and fast-paced online fury.
