The Conta series is one of the long-standing classics of video games, starting off in the era of the NES. It's a series of shooter games about two army dudes who battle against space aliens... or Earth terrorists who work with alien technology... or a group of robotic alien terrorists...

The series is really rather confused due to regional translation differences and censorship.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
