Cult role-playing game Undertale was created by indie developer Toby Fox and released in 2015. The game sees players exploring the monster-filled underground in an attempt to return to the surface, with three different endings available depending on how many enemies are killed during the adventure.
Undertale went on to sell more than five million copies and Fox released the sequel Deltarune last year, with more chapters planned in the near future.
Last year, Undertale celebrated its 10th anniversary with limited-edition merch and a livestreamed playthrough. Fox also released a 10th anniversary update to the game’s incredible soundtrack and now Square Enix have confirmed two more remix albums are in the works.

Set to launch later this month, ‘Undertale: Chitei De Chill’ is a collection of lo-fi and chill reworkings of classic Undertale anthems. “The melodies that once colored the underground world have been reborn as gentle chill sounds, creating a work that lets you experience a new side of Undertale,” reads the description. The record will feature 20 different tracks with the first five available to stream now.
Next month Square Enix will release ‘Undertale Piano Arrangement Album – Echoes Beneath’ which sees Yoko Shimomura reworking 15 of Fox’s original tracks to “deliver rich, expressive interpretations that rekindle the emotion and nostalgia of the original soundtrack.” The album can be pre-ordered here.

Reflecting on ten years of Undertale, Fox said: “I wanted the game to feel like it was responding to everything done by the player. Ideally, it should feel like there was always some new secret to find every time you did something in the game.”
In other news, long-awaited Silent Hill 2 movie adaptation, Return To Silent Hill, is being panned by critics ahead of its launch this Friday (January 23).
