World of Demons was a 2021 hack and slash video game developed by PlatinumGames.

World of Demons is broken up into individual chapters, in which the player completes combat challenges and puzzles to progress.

[4] World of Demons was announced in April 2018 as a partnership between PlatinumGames and DeNA, and was set to release later the same year as a free-to-play experience.

[9] GameSpot's Jason Fanelli praised the versatility of the combat system for encouraging strategizing with enemies, summarizing "it's fast and it's frantic, but most importantly, it's a lot of fun".

He criticized the game's "slow" camera controls and "unreliable" auto-target system, though noted he was usually able to avoid the latter through dodging.
