Gradius NEO Imperial is a horizontally-scrolling shooter game developed and published by Konami in March 1, 2004 for mobile phones, and was released on NTT DoCoMo's FOMA 900i line of phones in Japan.
In contrast to other Gradius games, players control the opposing force in form of a Big Core. However, since the Big Core that the player takes control in this game is a betrayer ship escaping from the Lars Empire, which is the enemy in Gradius NEO, players won't fight against the Gradius Union.
The Gradius NEO series appears as the Sequel of the last Nemesis game, Nemesis 3.
- Stage 1: Lars Empire Base
- Stage 2: Space Highway
- Stage 3: Lars Empire Fleet
- Stage 4: Asteroids Zone
- Stage 5: The Neutral Zone
- Stage 1: Big Core
- Stage 2: Satellite Core MK II
- Stage 3: Daedalus
- Stage 4: Crystal Moai
- Stage 5: Genocide Core
Big Core Custom is sucessful in escaping from the Lars Empire after destroying Genocide Core. Sadly, Force Viper destroys Big Core Custom, not knowing that that Big Core Custom was trying to escape from the Lars Empire. Big Core Custom's wreckage flows towards the sun. This is the only sad ending in the Gradius Series.
- The enemies in the game, Zebra and Wolfar, resemble the fighter craft known as the R-9 Leo from R-Type Leo and, slightly, the Silver-Hawks from the Darius series.
