Lies of P is a 2023 action role-playing game developed by Neowiz and Round8 Studio and published by Neowiz. A science fantasy horror story loosely based on the 1883 Italian novel The Adventures of Pinocchio by Carlo Collodi, to whom it is dedicated, the game is a Soulslike set in the fictional steampunk city of Krat, inspired by the Belle Époque. The titular "P" refers to protagonist Pinocchio, whom the player controls from a third-person perspective, and is one of the automaton-like "Puppets" central to the life and industry of Krat.

As Pinocchio, whose freedom of will and action bypasses Krat's laws of robotics, the player must use melee weapons, a mechanical arm, and a mysterious energy named "Ergo" serving as both XP and currency, to navigate the enemy-infested city, which is plagued by a "Frenzy" turning other Puppets homidical, a deadly epidemic, and multiple conspiracies, using a luxurious hotel as their base of operations. Throughout the story, binary choices by the player affect the outcomes of sub-plots as well as the overall story. Most of the game's characters are based on the novel's, with unnamed animals adapted into Humans with animal masks and codenames.

Lies of P was released for macOS, PlayStation 4, PlayStation 5, Windows, Xbox One, and Xbox Series X/S in September 2023. It received favorable reviews, with praise directed at its visuals, sound design, atmosphere and voice performances, though opinions on its narrative and gameplay were mixed. By June 2025, the game had sold over 3 million units and was nominated for several year-end accolades, including The Game Awards and the Golden Joystick Awards, appearing on numerous lists of the top video games of 2023. A prequel expansion, Overture, was released in June 2025. A sequel is in development.

Lies of P is an action role-playing game played from a third-person perspective. The player controls a silent puppet referred to as P, who traverses the fictional city of Krat and fights hostile puppets, factions, and citizens disfigured by the petrification disease. At the game's start, the player chooses one of three combat styles, which determines the character's attributes and initial weapons. The player uses melee weapons and Legion Arms equipped with tools that include a grappling hook. Every weapon, except for boss weapons, consists of a blade and a handle that can be upgraded and combined with other similar components. Upon combining, the weapon gains a unique ability called Fable Arts, activated when the corresponding bar is filled up. Weapon durability decreases during combat and can be increased by grindstones, which also give weapons temporary power-ups. The player can perform light and heavy attacks, as well as parry or block enemy attacks. Parrying inflicts a staggering effect on the enemy and damages their weapon. Blocking causes P to lose a small amount of health, which is partially restored after a successful counterattack.

The player acquires and upgrades weapons at Hotel Krat, which also provides access to other activities as the game progresses. Items are purchased with in-game currency called Ergo, also used to level up P by distributing it among vitality, vigor, and other attributes. The game features a skill tree that gradually unlocks with Quartz obtained after either buying it from a shop or defeating bosses and minibosses. Skills have additional slots for passive bonuses. After reaching a certain point in the story, the player can use Wishstones that grant temporary power-ups, such as increased damage and health regeneration to either P or a spectre. The player can also equip Defense Parts that increase P's defense capabilities. Before a boss fight, which usually has two phases, the player can summon a spectre to provide support. When the boss is defeated, the player receives a Rare Ergo crystal that can be exchanged for boss weapons or amulets with bonuses.

Exploring Krat, the player encounters ringing phones that pose riddles. Correct answers reward the player with Trinity Keys, which unlock locations containing gear and resources. The player can also find Cryptic Vessels, hidden locations with chests that offer various rewards, as well as collectables. Checkpoints called Stargazers are located throughout Krat and can be used to restore P's health and resources. Stargazers also serve as fast travel and respawn points. Upon respawn, P loses Ergo, which is retrievable at the place of death. However, each time P takes damage on the way back, the amount of recoverable Ergo decreases.

Lies of P features a morality system that presents the player with limited-time options: tell the truth or lie. These decisions influence the plot's development, including the ending. The player engages in conversations with non-player characters (NPCs) through a dialogue tree, uncovering additional information about the game world. Certain NPCs offer side quests that reward the player with items like new weapons and resources. P's appearance is customizable with outfits and masks found throughout the game. After completing the main story campaign, New Game Plus becomes available, allowing for replay with gear and upgrades acquired from the previous playthrough. The Overture expansion added new content, including enemies, weapons, side quests, and accessibility options, among other features.

Much of Lies of P's story is given to the player through optional dialogue and flavor text from items; when and if players learn of specific story elements can depend on their progress, although this section summarizes the story in a more linear fashion.
