Ninja Gaiden: Ragebound is a challenging 2D action-platformer that runs parallel to the original NES Ninja Gaiden, following ninja Kenji Mozu as he defends Hayabusa Village from demons using katana combat and the Guillotine Boost mechanic.

Expect a focused main story run to take 10-12 hours , with full completion pushing toward 15-20 hours due to tough bosses, side missions, and a post- game boss rush.

Playtime Breakdown

Completion Type| Estimated Time| Key Factors 137

Gameplay Structure

  • Acts 1-2 : Introduce Kenji and second character Kumori's playstyles, Hypercharge, and boosts amid demon fights.
  • Acts 3-4 : Soul-linked duo battles, crystal hunts, and a Demon Lord finale with multiple endings (choose Kenji or Kumori to seal the door).
  • Post-Game : Replay 4-6 for both endings to unlock boss rush—perfect for Ninja Gaiden diehards craving replay value.

Players on forums like GameFAQs and Reddit echo this: blind runs hit 15-20 hours initially, dropping to 5 on replays with practice. A full 100% S-rank walkthrough clocks in around 3.5 hours for pros, but most face deaths on bosses like Ryu Hayabusa or Obsidrae.

"Honestly - I think it would have taken me about 15-20 hours on blind run and 5 hours for a replay" – GameFAQs user

Released July 2025 by The Game Kitchen and Dotemu, it's hailed for NES-era difficulty on modern platforms—ideal if you love precise platforming and brutal combat. Since its launch last summer, forum buzz highlights its replayability, with no HowLongToBeat aggregate yet due to its niche status.

TL;DR : 10-12 hours for story, up to 20 for mastery—pure Ninja Gaiden punishment.
