Castle Town's Red Door

Step through the red door between Deltarune’s Castle Town and Undertale’s Ruins. Frisk leaves the Ruins and joins Kris, Susie and Ralsei as a fourth party member in Deltarune.

Deltarune stays the game you play: Frisk follows you at running speed, speaks with the group, appears beside them in battle, and has their own face, name, health bar, animated attack and free Check action. Their timed attack can damage enemies.

Solo play. Requires your own Windows copies of Deltarune (supported Chapter 2 or 3 game data) and Undertale Steam 1.08. Press Play in Melty; it starts both games and builds Frisk’s graphics from your installed Undertale copy. The release contains no game art or game data.
