After centuries and countless battles, our heroes have gone from one place to the next trying to save as many of their kind possible. But it comes to a point that the once hunters are now being hunted by the enemy they once fought against. You have gathered enough firepower and weapons to last for quite a while. If you come across an oil drum, hit it to gain health whilst shooting at weapon boxes will increase your firepower. By accumulating enough energy, you can fire your all-powerful G gun for devastating effects. Enjoy the thrills of shooting and being shot at in Metal Slug Death Defense.
