Hello everyone! 🌺
I’m creating an Undertale AU/fangame called Underpest: No Mercy.
This is an early-stage project (not a full game yet — currently concepts and ideas).
This is a fan project (no payment — made for passion).
World / Setting:
In this universe, red echoing flowers 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 only way to survive is to fight the infected.
Story:
The story follows Frisk and Flowey as they try to collect the 6 human SOULs and escape this destroyed world, while struggling to survive and explore what remains of the Underground.
Infected and Combat:
The infected have distorted voices and broken speech tied to their past memories.
Some newly infected monsters may still retain consciousness for a short time — they won’t attack immediately and may even ask for help.
It is possible to spare them, but this will have consequences, as they will eventually fully transform.
Environment:
Most areas are overrun by the flowers, which can block paths and make exploration more difficult.
During your journey, you can find or buy items that will help you in battles.
Collaboration:
I’m currently looking for collaborators — especially programmers (GameMaker) and artists — to help develop the project.
If you’re interested, my Discord is: super_soneco12
