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.

I don't have much to say, I had an army of water people, they were "Pillow talking" in my apartments, made some babies, babies grew up and helped fight off evil humans.
Then I found out that most of these ♥♥♥♥s were unemployed, so I evicted each and every one.

More monsters came, and more people behind on rent, so I sent them to their deaths. I now run an apartment complex that houses demons.

They pay, they kill, ♥♥♥♥ all else.
Being Satan the landlord is kind of fun.

Standard Game Rating
  • Story: 10/10
  • Gameplay: 9/10 (Tower Defense and Evicting Tenets Sim)
  • Presentation: 10/10 (Game looks good, like really good, I love the art style even if it's pretty simple.)
  • Soundtrack: 9/10 (it fit, it was cute)
  • Replayability: 8/10 (would come back to it late one night if I feel like playing a tower defense kind of game.)

Having never played any tower defense or micromanagement games, this is an amazing introduction to the genre. It's fun and witty. This is actually one of the most addictive games I've ever played.


You actually get attached to your characters and feel like the best landlord in the world even though you're Satan and your plans are actually to raise an army to destroy civilazation.
It makes you reflect on how you judge people in real life: You're not going to let an unemployed, cigarette butt collecting cheep cheep bird rent your property without some sort of social assistance.
The demons and monsters have kids, get promotions, etc.


If I was a real landlord, I wouldn't be giving into the creatures' unrealistic expectations. ie: Giving them a 3D TV.

This is actually some of the most fun I've had on my PC in the past month, Highly reccommended.

This game is too emotional for me

This is game is cute and cruel at the same time. All the reviews about those cruel and ridiculous events are all true.

A tower defense game where you are a landlord, taking care of monsters... or so I thought.

You have an absolute power over the occupants. My first playthrough I read every details of the game. The jobs my occupants have. Their satisfactory meter. I always check how they feel and what they want, trying my best to fulfill all of their wishes. There is an option to evict them, but I don't intend to use it at all. Later on, my cheepy is the first one to find his lover. And the first one to have a child/chick. I am so happy for them. I max out their satisfaction. And try my best not to increase the rent too high.

To my ignorance, this is not how you play the game. This is not sims! It's a tower defense game! You need money to upgrade your 'fort'. But my progress is really slow because I care too much about them. Those cheepies are extremely poor as they have low-income works. As time goes on, I accidentally kill the cheepy's lover. I fast-foward the time but I was too careless. For that, a cheepy lost his wife... and the child/chick lost his mother. Killed by those filthy humans that try to attack the building. I feel so bad about this. The early feeling of happiness has gone in the blink of an eye. Sorrow creeps into my heart.

To make things worse, the father-cheepy and the daugter-cheepy didn't say anything. But at least, I wanted them to complain, to at least blame me for I have done. They did none of that... as though they understand what was at stake.

Perhaps, they think that I am already kind enough to give them shelters against those dangerous humans. It could have been worse. The enemies only get much stronger with each quest.

I was quite shocked by the incident so I paused the game for a while.

Something must be done in order to fight against those vicious humans.

After much deliberation, I, the kindly landlord, evicted those remaining cheepies... They both pack things and leave obediently. They are both crying, yet firm and understanding. They know I need to make rooms for the stronger monsters.

Father and daughter.... now homeless... without wife or mother... Both of them... Hobos lol

The situation alleviates for a while. Stronger monsters now occupy the tragic-filled room of those cheepies. Completely unaware of the sacrifices I have to make.

Despite all this, the lesson I have learnt is not 'sacrifice have to be made' but rather 'Guilt can comsume the sanity of a man'. Unwilling to bear the emotional pain much longer, I seek the easy way out. Knowing only cowards would choose such a path. But at the time, believe it or not, I do not care. I just want to end the pain. Therefore, I committed suicide... (Or what one might call 'uninstalling the game')

One </3 heart out of One ❤

3/5 Would get stupidly emotional again.

Fun game that has you managing an apartment the devil. You fill rooms with different types of creatures(demons, elementals, etc.) to pay you rent while they live their daily lives... until the noble heroes show up to slay the devil(that's you!)! Then you need to send your minions out to protect you! It gets pretty difficult later on, so you have to make your minions mate to have stronger children. It still stays fresh though, it never gets old sending adorable chicks out to their death mwahahahaha...

Pretty addictive and charming management sim/tower defense hybrid.

Like the fact you play as the villains not the generic good guys.

Gameplay is simple but fun, with intuitive controls.

For little over a dollar (SGD), you can't go wrong with this game if you like these two genres.

Unholy Heights выглядит в точности так, как вы можете себе представить по страничке в Стиме. Это гибрид симулятора общежития в стиле Sims и Tower Defence, когда твои квартиранты защищают дом от злых крестьян с вилами.

Игрушка очень щадящая: деньги уходят только на то, что сам захочешь купить, плюс прорвавшиеся противники грабят хозяина досуха.

На уровне "заселения" достаточно минимально следить за потребностями приходящих монстров и оборудовать им соответствующие квартиры. Квартиранты заявляют свои требования, пока у вас живут, и если вы их выполняете, довольство жильцов растёт - а это увеличивает их параметры, помогая защищаться. Плюс, по мере того, как улучшается отношение всей расы жильцов, становятся доступны более продвинутые версии квартирантов. Ах, да, у определённых рас монстров взаимная нелюбовь, и если взять их одновременно, отношение к вам и довольство будут падать у обоих.

Часть с Tower Defence активируется, если вы возьмёте соответствующий квест. Общая сложность квеста показывается, но лучше ориентироваться всё-таки на стоимость награды, потому что индикация довольно грубая. Число и наименование квестов фиксировано, выполняются они только по одному разу, но в произвольном порядке, и по мере выполнения старых квестов досыпают новых. Если квестов не брать, ничего и не происходит - монстры будут жить своей жизнью и платить квартплату, да и всё. Ну, разве что, раз в пару дней зайдёт случайный противник, не представляющий никакой опасности. Есть специальные квесты, дающие новые предметы обстановки или как-то ещё меняющие ситуацию - в том числе всегда доступен один сюжетный квест, который двигает прогресс дальше, давая доступ к более сложным квестам.

В общем, это всё. Если интересно следить за жизнью своих монстров и обставлять квартиры мебелью; если интересует Tower Defence - поиграть можно. Но мне показалось как-то пустовато, доигрывать не буду.

If you tell people about a game where you play as satan, they’ll probably think of torturing innocent souls, razing cities, fighting against god… You know, wreaking havoc on an untold scale. That could work, but it probably wouldn’t be nearly as fun as what Unholy Heights’ developers thought of.

"The Devil’s spent his savings on a place in the projects!" is the line that opens the game. Satan now owns an apartment building, and has to bring monsters in as tenants to not only get some cash, but also to protect the place from foolish adventurers looking to slay him. Priorities, see, after all those folks are dead, and we’ve some money in the bank, then we’ll talk about that havoc, and about world domination.

You have a side view of the building. Whenever you’re attacked, the adventurer party will climb floor by floor, attempting to reach The Devil’s room, and you have to call on his tenants to prevent that from happening. When you're not under attack, you’ll need to recruit more tenants and keep them happy, so they’ll fight better and pay more rent. Of course, you aren’t above evicting them if they fail at either of those things.

It’s very engaging, not only because of the gameplay, but the cute cartoon-ish presentation keeps you attached to each monster as they form their families and advance in their careers. It’s hard not to like them, or not feel slightly saddened when they die or leave. But, back to mechanics, the engagement also owes a lot to the surprising amount of depth to the game.

Higher tier monsters have to be unlocked, and each has its own demands for that to happen, demands which aren’t always simple to meet. As you unlock those monsters, you’ll also need to mind the room allocation for battle: some monsters can tank more hits while others work better shooting from afar. To say nothing of the stat growth mechanics.

Still, you can learn most of it in a few hours, without worry. It is truly a gem of an indie game, bringing together management, tower defense and real-time strategy, and still remaining quite accessible. You will need to read guides if you go for 100% completion, but whether or not you decide to, Unholy Heights still offers incredible value for its low asking price of four dollars.

I was skeptical that this game would be like one of those diner simulation games, but the devs have found a way to combine real-time combat, leveling up, and economy management into a really unique, fun, and addictive game. I'm at work right now and I can't stop thinking about this game!

Extremely simple but addictive management and tower defense. Evil has scarcely been so cute. After two hours of playing I was still grinding away with a single-floor apartment building, so making progress (building more floors and raising more monster tenants) might turn out to be a bit of a timesink (suggesting it'd be an even better mobile game), but at least it's enjoyable and full of adorable artwork and catchy music found only in Japanese games of this type.

Once upon a time,there's a peaceful apartment in Unholy Height where demons love each other and have a family.Suddenly the legendary hero coming to your apartment to kill residence in an apartment.All demon including demon kids fighting against the legendary hero and intense battle happen*not really,the legendary hero too OP,dont open the door when he come,he dont have a key to enter a room haha.The Cheepy parents both dead and leaving its kid *thank you legendary hero,u are the best.The Cheepy kid dont have money to pay a rent,so the Devil(that's me!) let that cheepy kid to stay for free *after that i envict him because why not?.So the moral of the story demon also have feeling and emotion and now i hate human because of this game.

Well back to the review,This is the underrated game that i ever play in steam,great concept of tower defense game.Demon can have it's own partner to make a baby including skeleton! *dont ask me how they make kid,it's beyond my power.They also add a little management to makes this game more fun where u can place a furniture and ur tenants need to pay a rent.And watch out for tenants who ran away because they wont pay the rent and debt.Simple yet fun game,worth to play.

One thing to know about this game: It's adorable. It's not addicting, but it is a pretty good game to waste some time on, or just to try something new. It has its troll moments, and I was grinning at some of the dialogue the monsters made. You're the devil in this game. You don't take over the world or be evil, you simply give monsters a place to live, make sure they're satisfied to become stronger, watch them live their lives, and fight guilds off.

Butttt, getting into the deep side of this game.. You have to choose your tennants wisely. Depending on their job, they'll be able to pay the rent, more or less. If they're for example a window washer, obviously they'll be very poor and probably won't even be able to pay off 14g's worth of rent. You get rent every day, which lasts for about 30 seconds if you have x3 speed.

What's cute about it is that not only the artstyle is cute and cuddly but the literal whole story. I mean, the game has unholy in it, and you're playing as the devil. But it's really not that at all, it's just like a hotel tycoon game with monster characters. Not to mention you get to see your tennants running back home in the rain scared, poor tennants that aren't able to pay rent will usually have a nervous or timid status (but is still able to fight), and little baby skeletons and chicklings. <:

It's a bit strategic as well. Waiting to get a good monster that has a good job and has high damage in health is kind of the learning part to the game. You get to learn which jobs pay more unless of course you're an actual person and actually know how much an amateur boxer and/or an unpopular comic creator gets paid. Different monsters have different pleasures too, some guys like the room hot, some like it cold. Some don't care if it's clean, some really mind. Cheap furniture will suffice for beginning monsters but as you progress they're going to request for more expensive items - especially the demons. But the demons are pretty damn helpful in battle.

Speaking of battle, you do have to wait a while to start new quests, just so your monsters can regen health get a +1 on their attack, but I enjoy this kind of stuff.

Excuse my sleep deprived mind as I am only using %8 of my brain at the moment, but seriously, it's a dollar, or at least it is in the holiday sale, I wouldn't recommend buying it for the full $4. It should be worth $2 max.

Unholy Heights is a fun, casual . . . apartment-combat-simulator? Well, it's got some bits of micromanagement and a tad bit of combat mechanics. I'll go into much better detail below.

TLDR here and at the bottom for convience \/

TLDR; Overall, Unholy Heights is a fun micromanagement game with moderately deep but easy to understand combat mechanics (RTS), quirky (and sometimes adult) humor, and cute simplistic graphics. Despite a small language barrier, with a small amount of time the game is easily understood. Later parts of the game can get a bit grindy, so it's better suited for small bouts of play for some casual fun.

Just as a forewarning, the original developers' first language is not English. While the game is understandable and funny at times, this will be prevelant throughout the game. Some descriptions for items won't make sense. Explanations for important parts of the game are sometimes vague. I had to figure out a LOT by myself, and you will too since the Wiki (the only one I could find) is unfinished and doesn't shed much more light than the game. Luckily, it's not too hard but you will be scratching your head at first.

In Unholy Heights, you are . . . well, Satan himself. And you run apartments. Ironically, you hardly ever see yourself in this game apart from the beginning and a picture when you hover over your manager room. Immediately, you get monsters that want to move in. Just move in all the cute little monsters and you'll be fine, right?

Well, sorta. Other than taking care of these monsters, you have to fight off pesky humans that wander into your land. While the combat is a HUGE part of the game, it's fairly simple. Cilck on a door to bring out the monster you want to fight. If they're there, they'll come out. Of course, each monster has their own attributes to contribute to the fight (Range, attack type, and physical and magical defense).

Some monsters have 'perks' with different positives, the most common with "Stronger at -insert day/night/weather". While this sounds like it makes battles more interesting, you can't predict the weather or when the humans arrive so relying on this will screw you over. Improving your 'strategy' (when and where you release your monsters when you have attackers) is what you'll be doing most of the time in concerns to combat. Once you have a solid one down, it's just boosting up your monsters to match the enemies and hoping the ones you need are there when you need them.

This is where the apartment bits come into play. To get stronger monsters, you have to improve their apartments and make them happy. The happier they are, the stronger they get. Other than the obviously stronger higher tier monsters (unlocked through raising your interest/respect/like for the Devil and through completing 'Quests'), you can get stronger monsters through a couple having a baby. Randomly, one of your monsters will get a lover, and after a random number of 'Pillowtalks' they'll have a baby. When the baby grows up, they'll have significantly stonger stats then their parents.

"Reputation" with certain monster factions/races will play a part in what monsters you can use, house, and unlock. Some can't stand each other. Others worry about how well your treating your residents, while others focus on how often your resident die/how long they live. This means you may have to sacrifice one for the other, since their requirements will be the opposite of another. Once one faction hates you, don't expect to see them again unless you do something huge to get them to like you again. Once a faction likes you and you complete the quest, you unlock new and stronger tiers that have a new set of attributes and likes and dislikes on their apartment. It's very satisfying to unlock these new creatures able to use them and just brings new life to the game after you've played for a long while.

However, getting the stronger monsters to match the quests you have available can take some time. The difficulty increase is moderately steep, so even if you have a solid strategy you'll be grinding small random encouters to make money, waiting for rent to be paid, satisfy your monsters, and hopefully have them have babies. It's all random, so you'll be sitting there with the highest speed on waiting for things to happen. Hopefully you have a second monitor to watch things on; the game 'pauses' when you alt tab in both Fullscreen and Windowed mode. Luckily, watching your residents as they go about their life can be pretty entertaining, but even then you should probably take a break from this game every once and awhile to not get burned out on it.

TLDR; Overall, Unholy Heights is a fun micromanagement game with moderately deep but easy to understand combat mechanics (RTS), quirky (and sometimes adult) humor, and cute simplistic graphics. Despite a small language barrier, with a small amount of time the game is easily understood. Later parts of the game can get a bit grindy, so it's better suited for small bouts of play for some casual fun.

Unholy Heights is a cute little management sim, coupled with defending your building from attackers.

Keeping residents happy is simple enough, give them what they want and don't charge them too much for the room. Getting the residents to actually pay you is tougher, you have to balance not doing quests to give them time for work with doing quests for the big rewards. Sometimes even that won't lead them to pay you as particular monsters are just bad with money.

Residents find partners and can have babies with increased stats, making balancing the items in the room a bit more challenging, but still simple enough.

The combat is simple too, enemies come, you knock on the doors to call residents to fight. But they can't pass each other in the halls, so the order and timing of the door knocks is important.

A good time waster that will eat away the day.
