This is the 4th title in the Xevious series. It changes from the 2D format of the original to a 3D environment. You start off with the same viewpoint as the original, but later your camera is positioned above/behind the ship looking towards the action.
At the very beginning of the game, you have to cross a river. If you drop bombs at the edge of this you will get the secret message: "NAMCO ORIGINAL CREATED BY K. KENJO".
Xevious 3D/G+ (ゼビウス 3D/G+ Zebiusu 3D/G+ ) is a compilation of the Xevious arcade games for the PlayStation.
