DONTFORGET is a fan-made continuation of the indie role-playing game "UNDERTALE". Comprised of a singleplayer Story Mode and a multiplayer Online Mode, this project aims to expand on the world, mechanics, and meta elements of UNDERTALE and DELTARUNE in unique ways.

 

Both modes follow a new story set ten years after the events of a neutral route. A human named Harlow finds themselves lost in the Underground, a hidden world of monsters below the Earth's surface. In order to return home, they'll need to follow the guidance of their "Guardian Angel", a mysterious voice that answers their call for help.

​

In Story Mode, players will join Harlow and two unlikely allies as they embark on a journey across the Underground, delving deep into its darkest depths, in a new adventure set after the events of the "Alphys Ending" of UNDERTALE's neutral route.

 

In the multiplayer Online Mode, players can connect online to explore the worlds of UNDERTALE and DELTARUNE together with other players from around the globe! Encounter both new and familiar foes, embark on a plethora of quests, discover valuable loot, engage in exciting player-vs-player battles, and hang out together with friends!​ Undertale's signature morality system makes a return in random enemy encounters, allowing players to resolve battles peacefully, or use violence to earn experience points like in a typical RPG. Either playstyle can be used to make progress, with players working their way towards unlocking new equipment, unlockable characters, cosmetics, and more!

​

DONTFORGET also introduces brand-new mechanics to expand on Undertale's battle system, such as a new emotion system for enemies. Each enemy can have a random emotion when encountered, which will change how pacifist players will need to interact with them in order to resolve conflicts peacefully.
