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.

  • Take on quests at your pace to unlock new monsters and furniture.
  • Build a stronger army as residents have children far stronger than themselves.

  • Monster occupations, hobbies and desires are all procedurally generated to keep you on your toes.

Welcome to Unholy Heights, a cutesy 2D tower defense game with a lot of personality and charm. You are the devil that has just purchased a tenement. Just one tenement, there are no scenarios or anything, just this one tenement in the game. As time goes by, creatures will stop by to visit your apartment building, then they'll want to rent a room assuming you have free rooms. If you take them in, they'll take up residence.

This diverse array of creatures will then go about life. They'll head to work, sleep, eat, fall in love, have babies. You really have no control over what they do. The real game comes into play when at the end of the day and night cycle when a hero comes to your apartment to rob it and or kill your creatures. So what do you do to defend your building? Click on your doors to knock on them and they'll come out to fight. The only catch is will they might be at work and not in the apartment. Eventually, the creatures will come back from work and be able to fight if not start fighting when they bump into someone.

Each enemy has one of three types of attacks: melee, mid range and long range. Your foes will have the same style of attacks. Its a nice system and since each creature lives in a different room, you can wait for the enemies to get to the center of your building, then call the first and last apartment to pinch them where they can't run away. They can also do the same to you of course. If one of your creatures gets weak, simply click them again and they'll run away to their room, to your devil headquarters or away from the building.

These daily attacks are more and less a grind. They won't give you much gold. Instead your tenants will give you daily gold in rent. If you want the most gold, you'll take on quests by clicking the sign on your screen. These quests result in larger enemy amounts in usually 3 waves. These 3 waves take place in short amount of times, so make sure your creatures are healthy. Each of these quests has a star / difficulty rating and bonus gold for completing it. Some quests are mandatory in red, and others are optional, but the optional quests seem more like steps to the red quests.

If an enemy gets to the top of your building, they steal gold and try to get away with it. If an enemy makes it out alive, you'll fail the quest and can do it again. It is a very forgiving system that keeps you in the game with no real way to lose. You'll always have creatures wanting to move in if you have an empty building.

So what do you do with all of this gold? When you're not being attacked, you can click on a room and see the inhabitants of the room, along with everything in the room. The tenants will want specific things like CD Players, fans, playing cards, plants and so on. You'll need to buy them things and by doing so, your creatures will be able to gain defense, attack and so on.

You'll also be tasked with keeping your residents happy, which really seems easy enough. Every type of creature has different needs to become happy. Such as skeletons need to defeat enemies, one type needs to live amongst plants or it'll get sick and other creatures become happy or sad based on the overall joy of the tenement. Some of your creatures will become sad if there are creatures they hate living in the building. The bestiary shows everything.

You can raise or lower the rent, and creatures each have jobs, so if they can't meet the rent, they can fall behind. Then it is your choice, do you evict them? Lower their rent? Or just make rent free to keep the good creatures you've worked into deadly killers. When new creatures arrive you can see their job so you know if they're some deadbeat cigarette butt collector or just unemployed in general. That doesn't stop paying tenants from falling in love with unemployed creatures that do nothing.

Eventually, you'll be able to add more floors to your tenement, along with unlocking more types of creatures and objects for their homes. Not just that, but you'll see the creatures fall in love and later have babies. What does this all mean for you? When there are 2 creatures living together, that's just more attackers for you. Their babies will grow into adults and be able to fight as well. Creatures can only fall in love and breed with creatures of the same species. There are consumable items such as balloons that will help a resident find love, and erotic cakes that will help a couple make a baby. Of course there are less funny consumable items like health potions as well. Your creatures will gain health when they eat, so you don't really need to micromanage anything.

In all, this is a really quirky, one of a kind game that I can highly recommend. The only down side is there seems to be a lot of grinding before you can get through the quests. The game does a great job of explaining things especially compared to other sim games. The game also seems underpriced, but if they had different scenarios, I could understand them having a higher price. The game has the right amount of depth to keep me interested, without overwhelming me.

This is not a genre I tend to enjoy... I'd say tower defence (which is not a perfect description of the game, but it is fairly close) is one of my least enjoyed genres. Unholy Heights is something special though.

Unholy Heights gets me far more invested in the morality of my actions than pretty much any other game. In a game like Fable which toutes its morality focused gameplay, I will just shrug off the ultimatums. "Will you let most of the kingdom die?!" Yeah; they were all carbon copies of each other anyway. "Will you let your beloved get killed by the evil guy?!" Yeah... her hair is kinda weird.

But this game...

I have some families that I accidently let the parents die, and now the child doesn't have enough money to pay the rent, but I feel so bad that I let her keep her room for free as a means of apologizing for her loss.
And another family which has been falling behind on rent, but I don't want to kick them out because they just had a kid.
And another family that keeps telling me to change the wallpaper back and forth and they're great at defending the place but I just can't stand their implied bickering, so I send them out as soon as there's an assault with the hopes that one of them will perish and I can finally either leave the room with smutty wall paper or plain wall paper...

Two demons were renting a room. they had a child together. Then the parents died. The child had no job and couldn't pay me for the room, it was all alone on the world and it had only me to look after him. But i need money, so i evicted him. I was honestly surprised the game allowed that.

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

Well satan since you screwed up, you are being demoted to manager of a hotel in the middle of the desert congratulations!

Your hotel is called Unholy Heights, in which keeping the residents happy and defending against heros who dare to trespass is top priority. Heros will attempt to sneak in and steal your gold, to counter them you will use the monsters who reside in your hotel. You’re residence is perfectly safe as long as they reside in the room and don’t come out to face the heros. Resources will deplete as a result, though there is no way to game over.


+ Hotel Room placement matters
+ Monsters give clear indicators of needs
+ Monsters have families/jobs

Separating enemies by using the positions of hotel rooms is a good way to separate their forces and prevent tanks from protecting the glass-cannon type enemies. The monsters have a numerous weaknesses and strengths depending on how you use them, for example a long-range caster can be good for taking hits from magical spells with enough vitality since they have more magic resistance than your knights.

Monsters will get a bonus to their stats depending on their mood. Clicking on their rooms will provide you feedback on how to improve their residence. The amount you can tax them depends on the value of the room itself. The higher the room value the more you can tax without them feeling like they are getting ripped off. Once you hit a certain point you will notice that the monsters cannot afford the hotel with the job occupations they have, so you will either have to lower it, until they can get a promotion or find more prominent monsters.

Monsters can find lovers, and eventually make babies. Which also factors into how much they can afford apartment wise. So lowering it a bit after they make a baby until he becomes an adult and can hold a job is a recommended idea. Babies generally have superior stats to their parents so wanting to breed over and over again is recommended.

Gym equipment and combat both help increase the stats of your monsters. Increasing their happiness by fulfilling their needs and increasing the value of the apartments also lead to bonuses highlighted in blue that will give you big advantages.


The quests are arranged in 3 colors, red for main quest, green for unlocking monsters, and yellow for unlocking furniture. Only one quest will ever be red at any given time since its a single main quest, with various side quests you can accomplish. There are repeatable quests per hotel floor stage so you don’t have to worry about hitting a wall.

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.

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.

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...

This initially seemed like an interesting concept, but it got old quickly. Even at max speed, too much of play time is spent just sitting around waiting for things to happen, and it soon becomes clear that the best way to increase your fighting stength is to spend even more time sitting around waiting for things to happen. In short, it's grindy in the most boring way imaginable, without even a story to redeem it.

The only downside about this game is the guilt of having your cute tenants die

Recommended: This is definitely an example of a game where the art direction and that design will just brush some people the wrong way, being very "twee" in that strange sort of Japanese way, but if that doesn't bother you, what you'll find is a fairly well-designed and moderately-deep tower defense game.

I've played quite a few flash games that involved hotel management, and Unholy Heights does a good job of incorporating new mechanics to a classic genre.

If you like hotel simulators, monster themes, defense-based gameplay, and fairly casual pacing, then you will enjoy this game.

The aesthetics are nice - the detail in the characters is decent, and any upgrades you purchase for each room is never shown. The music and sounds are okay, nothing too special, although I personally like to mute the sounds in favor of my own.

The tutorial is quick and very helpful at showing you how every mechanic works. The learning curve is minimal to moderate, and it is easy to understand everything about the game with one or two short playthroughs. The pacing for the game is completely up to the player, as you can continue grinding until you wish to increase the difficulty (by purchasing the next floor for your apartment).

In the game, you play as the Devil, acting landlord of the Unholy Heights apartments. You can accept different monsters as tenants, and these units are called upon whenever you are attacked by adventurers. The monster types you can add as tenants increases as you progress through the game and build more floors (this also increases the overall difficulty).

Each monster has different desires, and purchasing their requests (room upgrades, like better computers, fridges, etc) will result in a satisfaction boost. This is useful because you can then increase the rent a little without incurring a penalty. At high levels of satisfaction, monsters will have bonuses to their abilities.

During battles, you can knock on doors to ask tenants to fight for you (this is an interesting mechanic, because monsters at work will be unavailable, however, monsters that are unemployed are also less likely to pay rent on time). Your monsters will fight in a line, so clicking on a monster who is about to die will allow them to retreat (and bring the next monster in line to the front). You can purchase one-time consumables (like health potions) that are used during battle and when a monster returns to his/her room. If you fail to kill an adventurer, he/she will take a percentage of your money - and escape with it if you are unable to kill them by the time they exit the screen. Saving often is encouraged, since you can have your entire tenant list destroyed if you make a mistake and/or do not plan accordingly.

Monsters can also meet mates (usually if they are employed and have better rooms), adding another person to your defense cue. Eventually, the couple can reproduce, earning you a third monster for a single room. Being able to keep families alive and happy is a great way to increase both your revenue and defense rating.

By default, adventures will appear fairly infrequently, however, you can access missions for gold rewards - a difficulty rating and brief description gives you an idea of what to expect. In order to build the next floor for your apartment, you must defeat a boss mission and have enough gold (quite expensive, so grinding is recommended).

Overall, the game is a nice, casual time filler. If you are interested in hotel management and/or defense games, definitely give this game a try (or at least take a look at the demo).

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!

For a game under 5 dollars, it's really not all that bad.
You let monsters into your apartment, you give them anything their annoying little hearts desire and they'll love you! Sometimes.

When I first played I couldn't bring myself to stop and go play something else. I was dead-set on breeding the strongest of monsters to conquer everything! Unfortunately doing the same thing over and over can get seriously mind numbing, so now I can only tolerate the game for about 15 minutes a sitting at the most. There isn't a real challenge to this game except for the occasional overly hard quest that you can still beat with minor patience. Still, it's a cute little game that won't forever be a blemish on your library.

Easy controls.
Easy gameplay but hard to master.
Tests how to micromanage each tenant and their room just to make them happy and ready for battle.
Many different monsters with different features and abilities.
Its repetitive but addicting.


Addicting but repetitive so yeah it can get tedious.
I wish you can personally assign room for the new tenants instead of them picking a random room.
I wish that there's a feature to refund all the purchased items in a room whenever a monster gets killed to avoid confusion on which to buy and not to buy for the new tenants because they're expensive and hard to track.
At some point of the game, not all monsters will visit the housing i mean i've been waiting for certain monsters to drop by and take that room because i need them to defend the place a lot better so that random generator dose not seem to work very well.

So the reason why i stil recommend this game is because despite of its imperfections the mechanic still works and probably by luck you will be able to win boss battles so that means patience is also the key to win this game. Specially when you wait for a tenant to get a partner then wait more until they make a baby then finally wait another for the last time till their kid grows old enough to fight for you... However its also a hit or miss because if that big family got too much debt for not paying the rent then you might lose them in the end so the game is basically a hit or miss chance.

Never the less its still fun and addicting anyways and the price justifies its quality.

UPDATE: 8-30-2014

I tried it again and i was a bit tolerant on late payers and it goes to show that most of them are willing to pay up overtime but one fled the room... lol its still amazing to see how this game behaves. :))

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.

This game was cuter than cute. It is a neat spin on the classic tower defense type games. The gameplay does get a bit repetitive after a while, but the upgrades and cuteness will override that pretty well.
