Ultraman Nexus (ウルトラマンネクサス Urutoraman Nekusasu) is based on the Ultraman Nexus TV series. The game includes characters from the 2004 movie ULTRAMAN.
Two basic characters are given at the start of the game (Nexus modes Junis and Junis Blue) in Versus mode. The other characters must be unlocked via Nexus mode. But some characters, (Noa, the One and Next) will be unlocked if you complete special tasks. In Nexus mode, you will appear in Anphans mode, until you battle the monster to a certain state, then you will evolve, becoming either Junis or Junis Blue (depending on the Dunamist you pick). If you die, you will become a Night Raider and travel through a forest to shoot at the monster until you can transform. In every 2 or 3 stages, you will face off against a boss (Dark Faust, Dark Mephisto or Dark Zagi). If you lose, the boss will revive one of the monster and you will have to shoot at it until you can transform again and destroy the monster. To unlock some monsters, you must die and fight the monster as a Night Raider.
