Gradius IV (or Gradius IV - Fukkatsu in Japan, fukkatsu means "rebirth" or "revival") is a horizontally scrolling shoot'em up developed and published by Konami. It was also released for Playstation 2 und PSP (as part of a compilation in both cases).

The game mixes pre-rendered graphics for small sprites with real-time 3D for larger objects, but is still a 2D shoot'em up. It has the same power-up system as other Gradius games. Certain formations of enemies or enemies with a different colour than normal leave behind power-ups. If you collect enough power ups, you can press a button to get an upgrade. All power-ups will be used and you get an upgrade depending on their number. You can choose between several upgrade schemes at the beginning of a game. For example, using one power-up will increase your speed, while two give you a missile shot. When you upgrade, you always use the total number of power-ups, so you have to be careful.
Power-ups that shine blue instead of orange are smartbombs and take out all enemies on screen.
