Quick answer (as of September 4, 2026): Onimusha: Way of the Sword is out today on PS5, Xbox Series X/S, Nintendo Switch 2 and PC, and early launch-day playthroughs put the main story at roughly 20–25 hours, with a completionist run that clears every side objective landing near 33 hours (Video Games Chronicle). It's a mostly linear, chapter-based game — not open-world — with optional side missions and hidden collectibles that pad the runtime. Crucially, a third difficulty called Carnage unlocks only after you finish the game once — it doubles as the game's New Game+, carrying over some progress — and many unlockables and items are gated behind that second run, so "beating" Onimusha and "100%-ing" it are two very different time investments.
Below is the full breakdown: story length versus completionist length, how the chapter structure actually works, what the Carnage post-game adds, and whether there's a New Game+. Everything here is sourced from the game's live launch coverage and Capcom's official listings — dated where the data is still settling on day one.
How long does Onimusha: Way of the Sword take to beat?
For a first, story-focused playthrough on the default difficulty, expect around 20–25 hours. That range is consistent across the earliest launch guides: Video Games Chronicle and G2A both put a mostly-critical-path run near the low end (~20 hours) and a more typical, moderately-exploratory run closer to 25 hours (G2A News). Pre-launch preview coverage had floated an unattributed "~20 hours" figure for months; the launch-day numbers land right on top of it, which is a good sign the estimate holds.
Three things move that number:
- Difficulty. Playing on the easier Story preset speeds you through fights; Action (the standard preset) is slower because encounters demand more parries and Issen timing.
- Exploration. The hub area of Eastern Kyoto can be expanded, opening up optional locations and objectives you can skip entirely on a story run (VGC).
- Collectible hunting. Hidden Lion Dogs are tucked into each area and give you a reason to revisit completed stages — pure optional time.
How long is a full completionist run? Video Games Chronicle reports you can clear every side mission in about a 33-hour playthrough — but notes that "many unlockables and items remain unavailable until you finish the game on Carnage difficulty, which is only available after finishing the game once." So a true 100% requires at least a partial second run. (Video Games Chronicle, September 2026)
Note that HowLongToBeat data is still thin on launch day — the community-submitted times will firm up over the first week as more players finish. Treat the 20–25h / 33h figures as strong early estimates rather than settled averages.
How is Onimusha: Way of the Sword structured — chapters or missions?
Onimusha: Way of the Sword is mostly linear and built around story missions, grouped in-game under the banner "Way of the Sword." You progress through a sequence of chapter-style stages as Miyamoto Musashi fights the Genma across a Malice-warped, Edo-period Kyoto, with a returnable hub in Eastern Kyoto that you can expand to unlock optional content (VGC).
How many chapters? Launch-day guides put the campaign at 22 story chapters (G2A News), and VGC's chapter list similarly frames it as roughly two dozen story missions under "Way of the Sword," bookended by the game's Formidable Foe boss duels (VGC). Capcom doesn't print a definitive chapter list on its own store pages, so treat 22 as the played-through community count rather than an official figure — ignore the auto-generated "wiki" farms that list far fewer missions.
What is clear about the structure:
- It is not an open-world game. Pre-launch, both PC Gamer and Game Informer previews stressed the full game has larger, more open areas than the linear demo, but is explicitly not open-world — and Steam's "Open World" user tag is wrong.
- Side missions are optional and layered on top of the critical path.
- Collectibles (Lion Dogs) and hub expansion exist specifically to encourage backtracking, which is where the gap between a 20-hour and a 33-hour run comes from.
What is Carnage difficulty and when does it unlock?
Onimusha: Way of the Sword ships with two difficulty presets from the start — Story and Action — and a third, harder tier called Carnage that unlocks only after you beat the game once (AltChar; PowerPyx). PC Gamer put it bluntly: "There's just one way to unlock Onimusha's harder difficulty level: finishing the game. No shortcuts, sorry!" (PC Gamer, September 2026).
Three important, verified details for planning your time:
- You can change Story/Action freely mid-run. The two starting presets can be swapped at any Spirit Mirror — the shrine-style checkpoints scattered through each stage — as many times as you like via the "Change Difficulty Level" entry. If Action gets punishing on a boss, drop to Story for the fight and switch back after; there's no penalty (AltChar).
- Carnage is one-way — once you pick it, you're locked in. Unlike Story and Action, you cannot switch out of Carnage once selected; it's a commitment for that whole run, and a single hit can kill you (PC Gamer; AltChar).
- Completion is gated behind Carnage. Because a chunk of unlockables and items only become available on Carnage, your "how long to 100%" clock includes a second playthrough on the hardest setting on top of your ~33-hour first-run cleanup (VGC).
This is the classic Onimusha / character-action loop: a tight first run, then a harder replay for the mastery rewards. It also fits what director Satoru Nihei said before launch — Capcom deliberately built the base game to be finishable and enjoyable, not a Soulslike wall, then layered the real challenge into the post-game. (For the full context on that debate, see our guide below on whether Onimusha is a Soulslike.)
Is there a New Game+ in Onimusha: Way of the Sword?
Yes — and it's tied directly to Carnage. Launch coverage confirms Carnage functions as a New Game+ mode: it carries over some of your progress from the completed save, so you're not starting your upgraded Musashi from zero when you take on the hardest setting (PC Gamer). That's what makes the post-game viable — you replay tougher, Malice-warped Kyoto against the same Genma with a head start, chasing the unlockables and items that were gated behind a second clear.
The trade-off, as covered above, is that choosing Carnage locks you into it — you can't drop back to Story or Action mid-run the way you can on a first playthrough. Capcom hasn't published a formal feature breakdown enumerating exactly which upgrades, charms and Oni Armaments transfer, so treat the fine print of the carry-over as something the community is still mapping. What's confirmed: finishing the game unlocks Carnage, Carnage is a progress-carrying New Game+ run, and it's the gate to full completion.

Should you rush the story or take your time?
If you're the type who plays once and moves on, a focused ~20–25 hour Action-preset run is the sweet spot — you'll see every boss duel and the full arc of Musashi's story without grinding side objectives. If you're a completionist, budget for the ~33-hour full clear plus a Carnage replay, and don't stress about missing Lion Dogs on the first pass since backtracking is baked into the design. Either way, use the Spirit Mirror difficulty swap as a pressure valve rather than committing to one preset for 25 hours.
Frequently Asked Questions
How long does Onimusha: Way of the Sword take to beat? A first, story-focused playthrough runs roughly 20–25 hours depending on difficulty and how much you explore. Clearing every side mission in a single run pushes it to about 33 hours, per launch-day coverage from Video Games Chronicle.
How many chapters are in Onimusha: Way of the Sword? Launch-day guides count 22 story chapters in the main campaign, grouped under "Way of the Sword." Capcom doesn't publish an official chapter list on its store pages, so 22 is the played-through community count — reliable early guides (G2A, VGC) converge on "roughly two dozen," while auto-generated wiki farms listing far fewer missions are inaccurate.
What difficulty levels does Onimusha: Way of the Sword have? Two presets are available from the start — Story (easier) and Action (standard) — and a third harder tier, Carnage, unlocks after you finish the game once. You can switch between Story and Action at any Spirit Mirror checkpoint.
How do you unlock Carnage difficulty? Beat the game once. As PC Gamer put it, "there's just one way to unlock Onimusha's harder difficulty level: finishing the game." Carnage is where many of the remaining unlockables and items live, so a full completion requires this second run.
Is Onimusha: Way of the Sword open world? No. It's a mostly linear, mission-based action game with an expandable Eastern Kyoto hub and optional side content. Steam's "Open World" user tag is inaccurate — pre-launch PC Gamer and Game Informer previews explicitly confirmed it is not open-world.
Is there a New Game+? Yes — Carnage difficulty is the New Game+ mode. Beating the game unlocks it, and it carries over some of your progress from the completed save, per PC Gamer. Note that once you select Carnage you're locked into it for that run; Capcom hasn't published a full breakdown of exactly what transfers, so the precise carry-over is still being mapped by players.
