Gradius III and IV

This is a compilation that includes two side-scrolling shooters developed by Konami. They are as follows:

• Gradius III
• Gradius IV

Both games are faithful recreations of their original versions found in arcades; however, additional features have been added (such as the ability to change the game’s difficulty and speed, a stage pick option, and other game types). In addition, a whole new introductory movie rendered in 3D was produced to present the games.
