A Musou brawler built on the bones of One Piece: mow down thousands of pirates across iconic arcs, pick from 40-plus characters, and watch buildings crumble under Luffy's Gear 4 fists.

One Piece Pirate Warriors 4 is a Musou-style hack-and-slash developed by Omega Force and published by Bandai Namco. You drop into large, destructible battlefields, beat hordes of cannon fodder into oblivion, capture bases, fulfill timed objectives, and slam into boss fights that actually ask something of you. The formula is Dynasty Warriors with One Piece DNA injected all the way through, and after more than four million copies sold worldwide it has become the fastest-selling entry in the Pirate Warriors series. The combat is where the game genuinely shines. Each of the 40-plus playable characters falls into one of four playstyles: Power, Speed, Technical, or Air. Sky-type fighters like Gear 4 Luffy can chain airborne combos for extended stretches, while Power types plant their feet and steamroll through armored enemies with brute force. You can slot up to four special skills per mission, including form transformations and timed buffs, and cooldowns are generous enough that you are almost always cycling through something spectacular. Boss encounters add a shield gauge you have to strip before landing stagger hits, which forces you off the mindless button-mash rhythm just enough to keep things interesting. Destructible environments round out the spectacle: smash enemies through walls, chain a ground combo into a launcher, and watch an entire building fold in the process. Three main modes structure your time: Dramatic Log is the condensed story mode covering six arcs from Alabasta through a game-original Wano conclusion, Treasure Log offers escalating standalone challenge missions, and Free Log lets you replay any completed stage as any unlocked character for grinding and experimentation. Online co-op is also available, which adds genuine replay value once the solo campaign winds down. Steam user sentiment sits at 93 percent positive across nearly five thousand reviews, which is about as clear a community endorsement as you will find. The weaknesses are real and worth naming. Mission structure grows repetitive during long sessions, level layouts can be confusing enough that objectives become a chore to locate, and the story mode is honestly a highlight reel rather than a proper retelling. If you have never watched or read One Piece, the narrative context will mean almost nothing to you, and some character-escort objectives assume you already know what every face in the roster looks like. The camera also struggles to keep up with the fastest Speed-type and Air-type characters, which can tip stylish play into frustration. All of that said: if you are a One Piece fan, or a Musou fan who can tolerate repetition in exchange for variety of character expression, this is the series at its highest point. The roster breadth, the destructible arenas, and the sheer visual commitment to replicating the anime's chaos give Pirate Warriors 4 a personality that outlasts most of its structural weaknesses.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
