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.

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
  • 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.

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.

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.

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.

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.

The real question is "Do male succubi exist?"

Neat and addictive game with a unique charm and flair to it. It's quirky and quite hilarious at times.

Cute flash game but has very shallow game mechanics and little replay value. Monsters are cute and presentation is acceptably straightforward. The strategy system is very arbitrary and cumbersome. Controlling your monsters in battle can be frustratingly tough because of the lack of any overlap, identical health bars for friendly and enemy, lack of hotkeys/hotgroups, stupid/unpredictable AI behavior, and no strategy interface to coordinate your forces or do anything complex. Upgrading apartments manually takes forever and often is counterintuitive because monsters will demand things they don't actually want or need and frequently when you satisfy requirements and make a really nice apartment the monster you just spent a lot of money pleasing will stop paying rent because now he can't afford it. These kinds of unnatural hurdles are everywhere in this game. Unique nouns in the game generally reference internet games and meme culture, as seems to be the popular tactic of late for flash games where the author doesn't want to do any creative work.

Overall Unholy Heights is not really worth spending money on unless it is VERY cheap and you've got nothing better to do than explore simple flash games. This one is charming at times, with an interesting premise, it just isn't very good.

Female skeleton cheated on husband/father of her child as male skeleton relieved himself while child skeleton slept.

Use chicken monsters as cannon fodder to attract more powerful and less totally useless monsters.

Evil soldiers stole my gold and no one can afford to pay 20G in rent.

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.

This is really a Great game for a cheap price! It's very much worth buying!

Unholy Heights puts together Tower defense and Hotel management simulation in one game. As the The Devil, attract customers (monsters in the game) and manage your hotel. Decorate your rooms with items that'll make your customers happy and content. The happier your customers, the stronger they get. At some point of the game, you'll be battling adventurers using the residents of your hotel. Be it a demon, undead, werewolves,it's up to you what combination you'll take. Each type of monsters have their own attitude towards items in the room and their neighbors so it'll be a challenge to balance all them. I won't spoil much, the rest of the awesome things in this game is up to you to discover!

My Personal Highlights for the game:
+ Has many events and interactions to discover.
+ The genre is unique and new. (Tower Defense/Management/Strategy)
+ Many monsters to unlock and to use.
+ The game is cheap. (bought it when it went on sale)
+ Has a great variety of missions. (Rarely redundant)
+ Has good art and gameplay
+ Highly Addictive game

I highly recommend it to anyone who loves tower defense and management simulations. :D
