Lords of the Fallen is an action RPG set in a fantasy universe where no sins are forgotten and the rulers aim to banish all sin from humankind. The protagonist, Harkyn, a criminal, carries his sins as runes on his face. He is convicted for crimes not revealed to the player. The human realm is attacked by an army of gods and Harkyn is released to fight them, as a chance for redemption. The linear story is divided into different acts that guide Harkyn and his mentor through the Rhogar dimensions inhabited by demons. He can form temporary alliances, but needs to travel into the heart of the realm. New areas are opened up by progressing, with the option to revisit earlier locations, and areas often have multiple paths with hidden locations.
The game features a combat style that can be chosen at the start, based on three magic types: brawling, deception, and solace, each with four specific spells. The player can choose from three equipment selections: cleric, rogue, and warrior, with a specific type of armour, weapon, and shield. By defeating enemies, experience is gained to unlock new skills and spells to use in combat. Fights often take place in close quarters, focusing on strategic use of attack, defense, dodging, and spells.
The game also features a system where the player can build up a multiplier by mixing different types of combo attacks, but also for avoiding checkpoints and saving up experience instead of spending it on skills. During combat, the player can lock onto opponents and timing is important to use the shield to block incoming attacks or perform chain attacks. The player's energy bar drains with each action and needs time to refill. Skills can be upgraded for overall statistics or for any of the three magic types based on spell points and attribute points.
The game is available on the Playstation 4, released on 2014-10-28 . The PC release has no regular edition, but it is released as a Deluxe Digital Edition with a digital artbook and map on Steam.
