One Piece: Pirate Warriors 4

One Piece: Pirate Warriors 4 (ワンピース海賊無双4, Wan Pīsu Kaizoku Musō Foa, lit. "One Piece: Pirates Unmatched 4") is the fourth entry in the One Piece: Pirate Warriors series.

Gameplay

 * Characters can now jump with, akin to several other mainline Koei Warriors titles of their own IPs.
 * Several characters' movesets are revamped to incorporate midair dashes and various new midair attack inputs. Some characters have singular midair attacks, or full-on midair strings.
 * Pressing during a string will initiate an air-juggling jump-launcher that carries both the player and their targets into the air, akin to an offensive jump cancel mechanic.
 * Several characters' base movesets on the ground are revamped via some moves having new animations, and old-recurring inputs being replaced with other attacks, and so forth.
 * A stamina system is introduced. Certain actions, such as Power Dashing, will consume stamina.
 * Stamina restores gradually when not attacking.
 * The Power Dash is a new dashing move that allows the character to knock back enemies while moving. It is performed by pressing . Holding down will increase the distance traveled. Power dashing consumes stamina. This is similar to the boosters from Dynasty Warriors: Gundam.
 * Charge Attack inputs (undefined) no longer have their own inverted strings. Though some still possess their own routes, while others function more like unique singular attacks akin to other games (or in some cases, the prior R1 Special Skill mechanic or the first installment's undefined attacks).
 * Special Moves/Attacks are now revamped alongside the aforementioned Special Skill mechanic, via pressing R1 and a face button (, undefined,, or ). Every character has a number of them above 4 total which in the preparation menus, can be customized/assigned to any R1 input as they desire.
 * Each special move has its own gauge which must be full before the move itself can be performed, and each gauge is filled by dealing and receiving damage.
 * Each special move has its own star rating, which indicates the power of the move, along with being able to level them up.
 * Two or more of their specials are reminiscent to the traditional Musou attack or the original special attack, with the same cinematic sequence style while also slowing down time during the animation.
 * One of their specials is instead a similar move akin to the above, but is mainly used to access special modes for a set duration known as a Full-Force Burst, replacing the original STYLE/HAKI Action and Kizuna Rush from the prior games.
 * This is a powered-up state which will boost the characters' stats. Some characters will Change Form, which will change their appearance, as well as change some of their attacks and combos.
 * During Full-Force Burst, the special move gauge tied to its input will gradually decrease.
 * Both a cinematic special and a Full-Force Burst however, will not have their cinematic angles occur depending on where the camera is angled in regards to walls, much like in the 2nd title.
 * A number of string/charge attack finishers from the prior title(s) for returning characters are now assigned to Special Attacks.
 * Giant enemies are now added to the game similar to the Mobile Armor bosses in Dynasty Warriors: Gundam 2.
 * Giant enemies will have an Armor Gauge, which must be reduced in order to deal meaningful damage to them.
 * When the Armor Gauge is reduced to zero, the giant enemy will lose one Shield Icon and enter a Broken Armor state. This is when they can be staggered, and will take more damage than normal.
 * Whittling down their number of Shield Icons will render the enemy into a Stunned State,
 * Maps are now more traditionally styled akin to the other mainline Koei games, where they are no longer grid-based with bases connected by corridors, and are now shaped in various forms.
 * A combo-hit-counter is now added.
 * The Crew Level system makes a return.
 * The leveling system has been omitted, and has been replaced by a new progression system. Characters are now upgraded through skill trees known as "Maps". Players spend Beli and coins to upgrade skills and unlock pathways to new skills. New Maps can be unlocked by raising a character's Crew Level.
