Storyline

Deltarune's narrative spans seven chapters, of which five have been released. Although it features characters and elements from Undertale, it takes place in a parallel universe distinct from that game's setting.

Gameplay

Deltarune is a role-playing video game with a top-down perspective. The player controls a human named Kris Dreemurr and has a party of other characters who they select actions for during battle. The game features both overworld and combat sections. In the overworld, the player can solve puzzles, collect items, and interact with characters and the environment. Different chapters introduce unique traversal mechanics, such as climbing, or statues that shift the game into a 2D platformer with action-based combat. Unlike Undertale, Deltarune does not have a random encounter system; instead, players can see the enemies in the environment before they encounter them, allowing for the possibility of avoiding or deliberately initiating combat. The game uses a turn-based combat system, where players can choose from a set of actions each turn: fight, act, item, spare, and defend. As in Undertale, players control a heart-shaped soul in a fixed area and must dodge enemy attacks in the form of bullets, though the exact mechanics are sometimes unique to the respective enemy. Defending or "grazing" an incoming attack by letting it come close to the heart without getting hit by it increases the tension points (TP) gauge, which allows party members to use spells or special abilities. For example, Ralsei can pacify tired enemies with a spell. Players may use acts and spells to spare enemies non-violently. The second chapter introduced the ability to use this strategy to recruit enemies to live in the player's Castle Town. Alternatively, fighting an enemy, which also increases TP, can lead to them being defeated violently. Starting in chapter 2, defeating enemies violently causes party members to gain HP and magic power after the battle ends, but enemies defeated this way cannot be recruited for the rest of the chapter.
