9 itemsAbout the Game

「Ninja Issen」 is a retro-style ninja platformer that features a variety of hyper action, 1 vs. many battles, and dynamic boss fights. Paying homage to the ninja games of the classic 8-16 bit era, 「Ninja Issen」 is full of ninjas, robots, neon lights, and dark atmosphere that overwhelms the streets of the future metropolis.
You will be 「Kiba」, a rogue ninja who was falsely accused of assassinating the grand master of his clan. In his desperate fight to escape from other ninjas trying to avenge his crime, 「Kiba」 suddenly finds himself in the middle of the world he has never seen.
THE GAME
In 「Ninja Issen」, you will always encounter 1 vs. many battles in which you must use everything to survive. The enemies come in many types and designs, large in number and ready to strike wherever you go.Fortunately, 「Kiba」 is a seasoned and skillful ninja who can overcome dangers ahead of him. Use 「Kiba」's weapons and abilities to cut down rushing enemies, and explore the future metropolis.
• KATANA - 「Kiba」's main weapon which is highly effective in close combat.
• SHURIKEN - Used for long-range attack and to deflect enemy projectile.
• TELEPORT - 「Kiba」 can teleport by throwing his katana to the spot he wishes to reach. Use it to jump between high structures and pass through traps like a pro ninja.
Combine 「Kiba」's weapons and ninja skills to make your own fighting style!
BOSS BATTLE
Each stage will have a boss that features unique patterns and gimmicks. As 「Kiba」, you will need to find out how to withstand their threatening attacks, and achieve victory in the end.
Sometimes the battle moves on to Phase 2 when the boss' HP reaches below a certain point. In Phase 2, the boss will show new and fiercer attack patterns. Destroying parts may also change the pattern of the boss.
