Deltarune
Updated: 12/11/2025, 8:10:36 AM Wikipedia source
Deltarune is an episodic role-playing video game by American indie developer Toby Fox. Set in a parallel universe to his 2015 game, Undertale, the game follows Kris, a human teenager predetermined to save the world alongside Susie, a monster, and Ralsei, a prince from the Dark World. Throughout the story, the party establishes relationships with a variety of allies and opponents. The game's combat system is turn-based and uses bullet hell mechanics. Like in Undertale, enemy encounters can be resolved peacefully or through violence. The game shares several characters and gameplay elements with Undertale, but takes place in a separate setting and features an overhauled battle system with multiple party members. Development for Deltarune began in 2012. Its first two chapters were released as free demos in 2018 and 2021 respectively, while the third and fourth chapters were made available in 2025 with its paid release. Subsequent chapters are planned as free updates. Initially released for macOS and Windows, it was later ported to the Nintendo Switch and PlayStation 4 in 2019, followed by the Nintendo Switch 2 and PlayStation 5 in 2025. The game has been praised by critics for its soundtrack, characters, narrative, and sense of humor.
