Gradius IV: Fukkatsu is the fourth arcade installment in a series of scrolling shooter video games produced by Konami. It was preceded by Gradius III, released in 1989, although other non-numbered spinoffs had been released such as Gradius Gaiden. This title brings a considerable graphical upgrade, particularly with the use of colored lighting. In addition, there have been several additions and removals to the vaulted weapons system; specifically, the edit mode has been removed and an online ranking system was added.
