MDK (Murder Death Kill) Abandonware

MDK (Murder Death Kill) is an action video game, specifically of third-person shooting

In this game you'll handle Kurt Hectic, one of the few human beings skilled in fighting who has survived a major alien invasion. Kurt's mission consists on the one hand of confining people to their homes and closing the cities. He will have to deactivate all the artifacts that the aliens have left hidden and at the same time he will have to charge all the artifacts that he can in his route.

It's a game with a good sense of humor. To carry out its missions Kurt has all kinds of vehicles and weapons, it is a free game because it is made in open source.
