Onimusha: Way of the Sword Post-Game Unlocks

Confirmed after the credits

Reviews written from completed playthroughs confirm that the game lets you continue on a cleared save or begin New Game Plus, and that Carnage difficulty unlocks at that point. Outfit unlocks are mentioned in the same coverage.

A completion guide documents Carnage as a post-clear unlock and records Boss Rematch alongside related trophy requirements, which separates mode unlocks from completion conditions.

Boss Rematch

Boss Rematch lets you replay boss encounters from a menu. That menu is also the basis for the most reliable boss count available — 18 main boss fights, following its order.

Beyond practice, it matters for completion because some trophy or achievement requirements are attached to it. If a fight went badly the first time, this is where you clean it up.

Planning a completion run

VGC estimates full completion at more than 60 hours and notes that certain items and unlocks relate to Carnage, which implies two runs. A thorough single playthrough is around 33 hours by comparison.

The efficient plan is a first run at your comfortable difficulty, then New Game Plus on Carnage for the difficulty-gated items, using Boss Rematch to fill any gaps.

Keep a post-credits save

Before starting New Game Plus, keep a manual save from immediately after the credits. Inheritance rules are not documented yet, so a spare save protects access to post-game content you have not finished.

This costs one save slot and removes the risk of discovering a rule the hard way.

What still needs verification

The specific outfit names, the exact carry-over rules for New Game Plus, individual trophy trigger conditions and whether any rewards can be permanently missed are not settled by the sources available.

Treat any published complete list — including ours — as provisional until it has been checked against a retail save. Where a source is a single reviewer's route, it may not reflect what every player unlocks.

Spoiler note and updates

Full boss, ending and outfit lists are inherently spoiler-heavy, so we keep the headline answer above spoiler-free and leave detailed lists to their own pages where you can choose to open them.

Capcom's Steam news feed is the place where post-launch patches, extra modes or changed unlock behaviour appear first, and any official change there will override early player findings on this page.

Continuing on a cleared save

Staying on your post-credits save is the low-friction option: you keep everything you built and can mop up side content and collectibles at your own pace.

This is the right choice if you are unsure what you missed. Nothing forces you into New Game Plus, and Boss Rematch is available for encounters you want to redo.

It also preserves the state you would otherwise risk when starting a new run, which matters while inheritance rules remain undocumented.

Carnage and the second playthrough

Carnage unlocks after the story and is the difficulty most players pair with New Game Plus. Because certain items are connected to it, a completion route effectively requires a second run.

That structure is what moves the estimate from about 33 hours for a thorough single run to more than 60 hours for full completion.

If you only want to see the game rather than complete it, none of this is obligatory. The campaign is finished at the credits.

How to plan a completion route

Work from the boss list and the chapter list rather than from memory. The most reliable third-party count is 18 main boss fights, ordered by the in-game Boss Rematch menu, and VGC published a full chapter breakdown.

Clear anything difficulty-independent on your cleared save first, then start New Game Plus on Carnage for the items that require it. That order avoids repeating work.

Keep notes on what you actually unlocked. Because outfit names and trophy conditions are still being verified, your own record is more reliable than an incomplete published list.

Confirmed versus unverified, at a glance

Confirmed: you can continue on a cleared save, start New Game Plus, play on Carnage, use Boss Rematch, and obtain some additional outfits and rewards. Those come from completed-playthrough reviews and a completion guide.

Unverified: the specific outfit names, the exact New Game Plus carry-over rules, individual trophy trigger conditions and whether anything can be permanently missed.

Keeping those two lists separate is the point of this page. A published list that blends them reads as authoritative while being partly guesswork.

How long the post-game takes

A thorough single playthrough runs about 33 hours, and full completion is estimated at more than 60 hours across two runs. The gap between those figures is essentially the post-game.

How much of that gap you close is a personal decision. Finishing the story is a complete experience on its own, and none of the post-game content is required to see it.

Sources behind this page

Mode unlocks come from completed-playthrough reviews and from a completion guide that documents Carnage as a post-clear unlock alongside Boss Rematch and related trophy requirements.

Time estimates come from a VGC guide that puts full completion past 60 hours and connects certain items to Carnage. None of these figures are published by Capcom.

Official Steam announcements are the channel to watch for changes, because a patch can adjust post-game behaviour after launch.
