A Deltarune x Undertale mashup. Kris, Susie and Ralsei wake up in a Dark World version of the Underground - and this time you fight it with Kris's whole party.
The Underground, with your party in it
- All five areas - Ruins, Snowdin, Waterfall, Hotland, New Home - each playing its real Undertale music, read from your copy.
- Deltarune-style party battles: FIGHT / ACT / ITEM / SPARE. Susie attacks and Ralsei heals automatically; KRIS is yours to dodge with.
- Undertale's bullet patterns: sweeping pellets, falling rain, bullet rings, aimed fireballs, blue and orange bones, falling spears, and telegraphed lasers.
- Every Undertale enemy plus all five bosses - Toriel, Papyrus, Undyne, Mettaton and Asgore - with their real themes and sprites. Bosses have multiple phases.
How to play
- Hold the arrow keys to walk the overworld. Random encounters happen as you go; the area boss waits at the end of each area.
- In battle: move KRIS with the arrows, confirm with Z. Use kind ACTs to spare enemies, or FIGHT them.
- Reads music and enemy sprites from your own Undertale folder - nothing is redistributed.
Requirements
- Steam Undertale. The game reads
mus_*.ogg files and sprite textures from your install.
Kris, Susie and Ralsei are original pixel art (Deltarune stores its textures in an undecodable format, so the party is drawn fresh).
