Unholy Heights is a mashup of Tower Defense and Apartment Management Simulation.
Recruit monsters to live in your apartment and fight for you when heroes attack!


Move monsters into your evil apartment building and start collecting rent to fill your coffers! Buy furniture and improve your tenants' rooms to make them happier. Adjust their rent to match their lifestyle to make them really happy!


The world of Unholy Heights is filled with all kinds of monsters waiting to move into your apartment, but they all have different needs. Some hate the cold, while some only feel at home surrounded by luxurious furnitiure. Make sure to keep your tenants happy, or they'll run out on you and their lease!


It's inevitable that rumors of an apartment building full of monsters would eventually reach the ears of the no-good humans. Would-be heroes, bloodthirsty pirates, cunning thieves and conniving mages all have their sights on The Devil's gold! Knock on doors and call your residents to your side! They want a war? We'll give 'em a war!


For those that enjoy the demo but don't want to start their slum over from the beginning in the full version, Unholy Heights' full version supports demo save transfer. Simply take the save file from your demo, drop it in the right folder, and start playing. If only world domination was that easy!

I guess it all started about four years ago.
I was working part time for my relatives, managing a block of apartments they owned.
One of the tenants suddenly moved away without paying their last rent payment or any other fees.
It was then that I knew.
"I'm going to make an indie game about this!"
Over time I noticed the number of apartments which had snowboards leaning against the side of their balconies increased, and that got me thinking [about the lives and hobbies of tenants] too.
I remember some (kinda creepy) old man telling me that he'd moved into the building because it was close to his workplace.
Before long he was shacking up with a young lady from one of the other apartments.
I guess that had an effect on me, too.
It was experiences like this that formed the basic concept for this indie game.
