Gunman Chronicles

It's high noon in deep space

It's been five years since you took control of the Gunmen, after the General fell in battle fighting the alien Xenomes.
Now the Xenomes are back in force, but this time there's a sinister presence controlling them. The infestation has taken a new, deadlier form and they're wiping out your forces.
You're on your own, facing a gang of genetically-engineered aliens and the desperados controlling them. Luckily you've brought your guns.... lots of them.
