"Naruto: Ultimate Battle" is a flash-based, 2D fighting game. Players take on the role of one of the characters from the eponymous anime and play through the chunin exams arc of the show. The chunin exams take the form of a fighting tournament. As is the case for the vast majority of flash games, there are no cheats; however, there are unlockable characters.
Kyuubi Naruto
When he was a small child, Naruto's village was attacked by a monstrously powerful nine-tailed fox demon named Kyuubi. The village ninja were unable to defeat Kyuubi, but they did seal it away in Naruto. This occurred before the original anime, but has been recounted in the series. In times of great stress, Naruto can draw on the demon's power, becoming an unstoppable opponent. To unlock Kyuubi Naruto and play as his character, first you must play as Naruto and press the "Special" button and the "Up" button. This will temporarily transform Naruto into Kyuubi Naruto. Do this five times, and you can select Kyuubi Naruto as your character.
Kakashi
Kakashi Hatake is a powerful ninja from Naruto's village. He is one of Naruto's teachers, and the leader of Team 7, the students who fight alongside Naruto in the chunin exam tournament. He uses elemental jutsu attacks, including lightning, earth, water, and fire. To unlock him, beat the game three times, once as Naruto, once as Sasuke, and once as Sakura.
Orochimaru
Orochimaru is the main antagonist of the first arc of the Naruto series, and he plays a major role in the second part. Orochimaru's overriding goal is to learn every jutsu and fighting technique in the world, and he often stoops to human experimentation and outright murder to accomplish this. To play as Orochimaru, play the game as Naruto twice, Sasuke twice, Sakura twice, Rock Lee twice, and Neji twice. This will make Orochimaru appear in the character selection screen.
Extreme Mode
Beating the game three times, once on Easy, once on Normal, and once on Hard will unlock the hardest game setting, Extreme Mode. In Extreme Mode opponents are quicker, are more aggressive, take less damage, and deal more damage to you.
