Hello! 🌺

I’m creating an Undertale AU/fangame called Underpest: No Mercy.

(This is a volunteer fan project with no payment — made out of passion and for fun.)

Note: This image is only concept art and does not represent the final game.

 Story Concept:

In this universe, red echoing flowers begin to spread across the Underground, infecting monsters and turning them into violent, starving, zombie-like creatures.

In this world, there is no option to spare — the infected are no longer themselves.

The only way to survive is to fight.

Story:

The story follows Frisk and Flowey as they try to collect the 6 human SOULs and escape a destroyed and infected Underground while exploring what remains of this world.

🌺 Looking for collaborators:

I’m currently looking for:

Programmers (especially GameMaker)

Pixel artists
