Here's a Showcase for the Extended Old Home! (While most of it layout is finished, stuff like collisions and tiles depths are not working yet, and some other little issues.) Also I swear I needed re-record that showcase several times.

UNDERTALE: Extended Underground Mod - Questions and Answers Open!

i had been discussing with some team members about the layout of the underground, and we had so much discussions that i decided rework the map of the extended underground. here it is the uteu map v3 i might gonna make a sprite version of it anytime.

One of the Team members (@tntaro ) made a sketch for the Old Home (abandoned) Station, but I guess I probably gonna use that design for the other stations (each one having it own design). Concept Art / Full Sprite / In-Game

After you finish Catacombs Quest, and make the True or Perfect Pacifist ending, and return to the Catacombs Graveyard, you gonna find Carol, on Rudy's grave. (Rudy's Grave drawn by myself, Carol Sprite edited by myself too.)

"Where you gonna go now?" (Kinda an concept art for the map system of Extended Underground mod.)

"10 years had passed since the barrier was broken, and monsters started living with humans again." "But what you gonna do after all?"

OVERSTORY (a random UNDERTALE sequel concept.)

still working in the extended old home.

rough sketch for old home extended layout (some previous rooms gonna be repurposed to be fit on catacombs replacing.)
