About This Game

The Devil has converted a tenement building into monsters-only housing in Unholy Heights, a mashup of Tower Defense and Apartment Management Simulation. Sucker monsters into moving into your building, charge them rent and keep them happy by buying them furniture.

Unfortunately, heroes have caught wind of the Devil's plan, and will stop at nothing to wipe him out. Knock on residents' doors to call them to battle, trap heroes in devious pincer formations, and command your troops to victory. Monsters get jobs, fall in love, have children, and even skip out on their rent. Keep them happy or you might not have anyone to fight for you when heroes come knocking.

Being a landlord is a difficult job, but it can't be harder than running Hell...right?

Key Features

  • Every monster is different. Some are lazy. Some are strong. Some are perverts.
  • Use an intuitive mouse-based control scheme to command your troops into battle.
  • Encounter more than 20 different monster species, and take their money.
  • Build a reputation with different monster families based on your performance and play style.
  • Take on quests at your pace to unlock new monsters and furniture.
  • Build a stronger army as residents have children far stronger than themselves.
  • Get monsters in the mood for love with inappropriately shaped erotic cakes.
  • Look on in horror as lovingly hand-drawn monsters and humans horribly slaughter each other over money.
  • Monster occupations, hobbies and desires are all procedurally generated to keep you on your toes.

System Requirements

    • OS: Windows XP (SP3 or newer) / Vista (SP1 or newer) / 7
    • Processor: Pentium III 1.0GHz or faster
    • Memory: 1 GB RAM
    • Graphics: Shader Model 2.0 or better
    • Hard Drive: 50 MB available space

A classy little tower defense/rpg hybrid where you're a demon overlord letting minions of your domain live in apartments.... Interested yet?

You get a wide variety of tenants all with their own strengths, weaknesses, and personalities (some have wet dreams and read dirty fanfiction.... relatable yet?)

In all seriousness it's a rather fun little game that at least deserves a try.... it has a NISA feel to it as well so if you've played something like "What did I do to deserve this my lord?" It's the same concept.... Keep the overlord safe from heroes.

got this one during the summer sale and was really happy with the outcome :) its a very cute tower defense game that starts off all nice and easy and then you start getting yo a** handed too and you realize how hard this game gets and the sad events that take place to these cute creatures in the game. the game is cool in the since that you recruit creatures by letting them move in into a complex (which you have to keep them happy by buying them what they want and lowering the rent price to what they like or else they get sad which is not good.) now you earn gold by doing quests and killing enimies that try to attack. Now easily the most annoying part of the game is when you are in battle and one of the creatures decides to go on a walk right before the complex is attacked which can get a bit annoying. you just have to learn when to start a quest what type of creatures to have etc etc. when you lose a battle you don't just restart you lose money and all the creatures that were there are dead forever you have to get new creatures to move in and it really does suck but its a part of the game. for the price that the game is at I say it is a must own on steam! Overall really fun but hard defense tower game but I would say give it a try!

Unholy Heights is a strange, strange little game. It seems to take itself fairly seriously, although there was obviously alot lost in translation when converting to English.

Myself, the white devil with the hitler 'stash, lured potential tenants with 'pervy' wallpaper, cigarette butts, and cheap rent, among other things. This is a tower defense game mixed with clan micromanagement. You run a block of apartments and the tenants are your 'towers'.

I will vote this a 'yes' but will curb-stomp it as well.

+There is a difficult learning curve (although good tutorials) that keeps you coming back for more like 'I gotta try to get that second layer!'
+Unintended humor through very bizarre descriptions of things
+Beware that there are lots of adult themes despite its kiddie cover - horse people mating, chickens having wet dreams, and demi-gods examining pelvises

-Menus are fairly horrible - the hotbar is pretty dumb - things could be much better optimized as far as mouse and keyboard setup
-Elevator music is generic
-Although the art all matches up, we are mixing demons with baby chicks and humans and demi-gods
-You have two screen resolution options - bad, and worse

Its cheap and we laughed at alot of it. Get it on sale if this looks like your kind of thang.

Let me tell you about Popan.

Popan was the first baby ever born in my apartments. She was a Cheepy so I didn't have high expectations. Popan was probably 3 days old when her parents died in an unfortunate ambush on my complex. I had a ton of other tenants, so I didn't see the harm in waiting for her to grow up. Somehow, she never became in debt. This ♥♥♥♥ing baby was paying the rent. She grew up to be a total badass. She would single-handedly wipe out entire waves of enemies without breaking a sweat.

Popan is obviously popular and well-known throughout the land, she easily finds herself a guy to shack up with. He's weak and dim-witted; a farmer named Peecone that watches tv 90% of the time that he's home. It doesn't slow Popan down though, she easily slays the first main quest adventurer all by herself while all the other tenants are at work. She returns immediately and has victory "pillow-talking" and immediately has the child they have been trying so hard to have. A girl named Chaan, that is impossibly strong as well. Popan and Chaan were ♥♥♥♥ing ruthless, the perfect mother-daughter duo. Then Peecone stops paying rent, or so I assume, as I thought the world of those two divas but not so highly of farmer Peecone. I keep lowering the rent hoping they'll stay, I evict Peecone hoping it will fix the problem. It helps! They are back in the green in no time and happily tending their garden and watching tv together. Then it all goes down hill again. Popan robs the cradle with her next man, the neighbor boy, Pyo, not much older than her daughter moves in. Things get tense. Chaan was the one that wanted the damn Love Balloon and yet her mother was the one to snatch up a mate. Chaan is unemployed but barely comes home. Popan and Pyo are having pillowtalk near constantly. Twice I found Chaan begrudgingly lifting weights while the two love birds pillowtalk all night, draining the life out of her having to deal with it.

Then tragedy struck. Being the only one home at the time of the ambush, Pyo the live-in boyfriend was struck down. Despite her envy, Chaan became increasingly more withdrawn, very rarely going out for fun or even job interviews. Popan also began getting increasingly more gloomy and soon they were once again behind on rent, once again because of a guy. In fear of losing my glorious lady warriors, I lowered the rent as much as I could stand but their grief had drained not only their livelihood, but also apparently their bank accounts because the two ♥♥♥♥♥es ran out on me in the middle of the night.

11/10 would collect rent from orphan babies again

Very cute and yet incredibly realistic in many aspects. Think of it this way: If you were a landlord, housing real monsters and treated them as most landlords do, this game would tell the story well. However the question lies: How nice are you to your tenants? That's what really makes the game interesting, and thinking of it that way, I have learned many things from this game:

-That Male Succubi are not Incubi but Dickgirl Succubi. 100% capable of having children.
-Skeletons are somehow able to reproduce...
-That Fishy Ones originally gave birth to the Pul-Pymesy
-That cats can tame dogs
-Most importantly, that I am a cruel dictator, and apon the discovery of a rather large debt or unemployment is punishable by death. Also the Demi-humans hate me.

10/10 Would recommend.
