Update V.1.4. - Unity 5, Oculus CV1 Support, Birthday Sale


It's been a while since our last update, but this weekend we're celebrating Monstrum's 1st proper birthday! We have a couple of things in store that we hinted about in the forums yesterday.

Firstly, we're holding a special birthday sale from Friday the 20th of May to Monday the 23rd of May! This weekend you'll be able to grab Monstrum, it's soundtrack, or the newly added bundle option for 75% off! If you've been waiting to pull the trigger, or have friends that have been wanting to jump in then this weekend is the time!

Secondly, we're pushing out a new patch for Monstrum. While the game hasn't been our main focus at Junkfish Towers we decided to update Monstrum's Engine from Unity 4 to Unity 5! This update brings with it a host of new fixes, including some overdue performance improvements that a lot of you have been waiting on. You can find a full changelog at the bottom, and it should be out later today!

Thirdly, Monstrum is now compatible with the Oculus CV1 headset! The upgrade to Unity 5 has allowed us to upgrade to the latest Oculus runtime, bringing the new features and improvements they have provided. If you own a DK1 or DK2 then don't fret! We still have support for you folks too, and you should see some improvements too!

As a quick heads up, engine changes may result in some new issues that we may not have found during our own testing, so if anything does happen please let us know in our pinned Bug Thread.

Finally, we want to thank all of you: the players, the streamers, the news hounds, the people who dropped by our booths at various shows, the other developers we've met, the people who put together an unofficial wiki, that person that stuck Monstrum on TVTropes, and everyone else from across the globe for your support and appreciation over the past year (and a bit). The response to Monstrum has been amazing so far, and we'd love it if you would help spread the word about the game even further this weekend.

We look forward to showing you what we've been up to in the coming months!

Team Junkfish

About This Game

Monstrum takes the traditional survival horror formula and remixes it completely with procedurally generated levels, permadeath, and AI driven predators, ensuring that nowhere on its derelict cargo ship is ever truly safe.

Offering up a challenge to even the hardiest of gamers, Monstrum will force you to use your wits and whatever tools you can find to outrun or outsmart your pursuer. Attempt to escape from an environment that is out to kill you while evading the lurking terror that could be around any corner. Can you survive Monstrum?

Game Features

Three Unique Monsters

Face one of three monster types each play-through, each one with different behaviours and tactics. Can you work your way out of an ambush or escape a direct attack? And will the same actions work every time?

Procedural Arena

Prepare for a different gameplay environment each time you play as the ship's interior shifts shape with every run, changing the location of items along the way.

Escape Routes

Discover different methods of escape and delve into the bowels of the ship to recover items you need to repair them.

Opportunities and Hazards

Use whatever you can find to try and outwit the monster. Hide in lockers or under furniture. Use distractions to attract the monster to you, or, perhaps more wisely, to where you've just been, but be careful not to run too fast lest you fall into one of the ships numerous traps along the way.


Death is death. Get killed in Monstrum and you'll be starting again. In a different ship, probably against a different monster. Good luck. Start running.

Being chased in a game gets me worse than anything else. I can deal with spooky ambiance and deadly monsters, and as much as I hate jumpscares they're at least over in an instant. But the sensation of being hunted, being pursued, quickens my pulse like nothing else. Quite a few games play on that fear, and Monstrum might be one of the most effective, as long as you can look past its limitations.

Monstrum drops you, the unnamed protagonist, onto a derelict cargo ship and challenges you to escape. There are three ways off this deathtrap, but each requires a spread of items that must be collected from around the ship. The layout of the ship is randomized every time you play, as are the item locations and your own starting position, so don't expect to memorize any of the key locations. Every attempt is going to take significant snooping around, from the engine room all the way up to the observation deck.

You're being hunted during this endeavor, of course, by one of three creatures. Each is unique in how it detects you, how it searches for you, and how it catches you. There's no teleporting here, either... these things know how to hunt, and will even lay traps for you. Fortunately every room has features like cabinets and beds that you can use to hide, and there are items to find that can distract the monster with noise or scare it off with fire. If you play your cards right you can give them the slip for a time but they are very aggressive in seeking you out. Also, fair warning, once you gather the items for an escape you have to distract the monster for a short time while your vehicle gasses up, otherwise they can smash it and cut off that option permanently.

Speaking of permanence, you get one shot at every game of Monstrum. Yes, this is a horror roguelike; every time you play the ship is randomized, and when you die you get to start all over. It's not a bad setup, because the different monsters keep things fresh and a single round should last you 20-30 minutes unless you keep getting your escapes cut off. That permadeath element helps heighten the tension as well, especially as you close in on completing an escape. Despite the variations in monsters and layout, though, you're still going to be on a derelict ship every time. And that means a lot of samey corridors and stairways and supply cabinets. You might be taking different turns to get to the next room, but it's all going to look very familiar very fast. It might also be an unpleasant experience, too, because the field of vision is unusually small. Coupled with the tight corridors, I started getting motion sick not 20 minutes in.

While I'm skeptical of how long Monstrum can maintain its appeal, I can't deny how effective it is while it has you. Being stalked by the monsters is a terrifying experience, aided by some sharp, gritty graphics and awfully effective sound cues. The ship feels utterly isolated and unwelcoming, and only becomes moreso when the creature catches wind of you. It works like a pocket roguelike Alien: Isolation, pitting you against a lethal stalker with just enough differences to get you to give it one more try. I mean, I had to tap out after just a few attempts because I was getting rattled so bad, and that has to count for something.

I felt awful playing this game on my DK2, but its still absolutely fantastic game.

When I decided to hang up my headset and play the game without it I still managed to jump out of my skin about 10 times.
The graphics are not the best ever, however the game is that immersive that you dont need good graphics!

Definitely worth the money, would buy again!

So I've only played this game for a whopping 20 minutes. However, in those 20 minutes I have nearly ♥♥♥♥♥♥ myself 20 times. I have only played the game in VR (It has a VR option during launch) and I can barely play it because I'm too scared. To be fair, though, any horror game (in my opinion) is significantly more terrifying when playing it in VR.

Here's what I have to say about the VR aspects of the game:
As I said, VR makes this game so much scarier; I can hardly play it. I keep trying to, but I can't get through it at all.
When I do play it though, I play it for about 5 minutes at a time before I wimp out and turn it off. The way the game is with camera controls and movement relative to the VR perspective, it's one of the very few VR games that starts to make my stomach hurt; I can't play it for too long before I start feeling sick.

That being said, neither I not you HAVE to play this game in VR, so many of those issues above can be avoided.

The game is really well made and very scary and it's procedurally generated so each time you play is different! Which is always a bonus! So every time that I've restarted the game after getting too scared, it's always different (for better or worse).

Great horror game. Great VR horror game.

This is a great horror game that is begging for an expansion. It's simple: you are stranded on a cargo ship, "alone", and you must find a way off. There are three damaged avenues of escape that all require various items scattered about the ship in order to be fixed. While you are searching through the confusing and disorienting hallways of the ship, you are being stalked by one of three monsters.

Each monster has its own personality and style. One is loud, fast, in your face, and impossible to shake. Another is ethereal, quiet, smart, and gosh darn scary. Another is sneaky, patient, and... well, actually, not as scary. To be honest, the monsters described as the Brute and the Fiend are the hardest and most fun. The Hunter is absent, not as scary, and (relatively speaking) the easiest of the bunch. I feel like the AI of the Hunter could be adjusted.

But regardless of which monster you face in your playthrough, the game is very difficult and very suspenseful. It's best played in a dark room with friends. When you die, it's someone else's turn.

I definitely recommend this game - if it's on sale. It really needs an update that makes the Hunter have a better presence and perhaps adds a fourth monster.

Actually the Best single-player survival Horror. You have to escape from the ship and find objects before monster finds you.

+There are different monster types
+Monster is very cunning: he lurks at you all the time
+The environment reacts when the monster goes, like the light flickering
+Game is very challenging: objects spawn randomly, also you start from different places each time

-Lack of tutorial
-No coop or online game

If you like Stealth and lone-wolf gameplay, this is the game for you
If you wish for coop and match try Splinter Cell Chaos Theory or Conviction

I like the fact that the game is scary and beautiful with graphics. But, It's too stressful. It's too repetetive. There needs to be a save system. I hate the fact that the monsters just follow you around! I also hate the hunter mechanism. I once had the hunter in a playthrough, and I went in a room for 2 senconds and when I come out, I see egg sacs everywhere. Just, HOW??
I hate the fact that you actually die after falling off deck 7! How can the player be so wimpy? I hate the security cameras!
They're so annoying! You have to wait for them to turn around!

Horror is my favorite game genre because it invokes so much emotion. Unlike a horror movie, if there is something you don't like you can't just look away and pretend the threat isn't there. In a horror video game you need to act or else you will die. This is true for any horror game, but I think it is the most true for Monstrum. Why? Well for a few big reasons:

1) The environment is random every time you play. Because of this, you feel lost every time and you need to build an incredibly vague map in your head on where you have already been and where you need to go next. It's like the worst scavenger hunt you can imagine yourself being in. It's a frickin nightmare.

2) The monster is chosen randomly each time. The beginning of each new game is always terrifying because you have no idea what is after you until it gets close. Each monster is terrifying in it's own way. They are either loud and terrifying to look at, or really fast and hard to see. Each monster is scary in their own unique way, making each experience fresh. When you get seen you need to make extremely quick decisions on where and when you should hide.

3) The monsters don't f**k around. You have to run as soon as they see you. LIKE RIGHT WHEN IT HAPPENS you better have a finger on the shift key and hauling ♥♥♥ out of there.

Basically, this game takes what is consistently scary (the unknown) and puts it into every aspect of the game. Unknown layout, unknown item placement, and unknown enemy and turns it into a great experience. I still have yet to beat the game after all this time, and I actually love that about it. It should be this hard. It should make you feel like the terror is greater than your courage.

The terror is smarter than you. The terror is better than you. But you are going to do everything you can to fight it and escape.

This is the best horror game on Steam hands down and well worth the price. Get it.

Here's a brief summary of my first 3 playthroughs, since you can find comparisons and pros/cons all over the place.

1st: While exploring a room, began to hear noises very close by. After sitting for several minutes, and not wanting to seem like a wimp infront of my girlfriend, I opened the rusty iron door infront of me. Immedietely upon looking left some purple phantasm sucked the life of of my while I screamed like a girl. Mission failed.

2nd: After once again hearing a monster whilst in a room, I determined the noise was above me, and leisurely walked out into the hallway. Two seconds later I began second guessing myself and made for a dead sprint, only to run straight into a huge red glowing thing that hugged me to death. Screamed like a wimp for the second time.

3rd: Having smartened up, I finally decided hiding when monsters were nearby was the best tactic. After opening a door and seeing a thin, translucent skeleton down the hall, I quickly closed the door then got down and crawled under a bed. "Surely my superior wit will save me this time!" I thought, only to watch as the creature entered the room and proceeded to drag me, kicking and screaming, out from under the bed.

Overall, 10/10.
Will continue screaming like a wimp infront of gf.

Loving this game at the moment. A very good cat-and-mouse horror game. It feels fresh each time you play due to the random layouts and starting each session not knowing which monster is after you.

It's let down by a few glitches and the occasional unfair death. It would really benefit from allowing you to save your sessions, as playing for 1 and a half hours only to get stuck in a set of drawers and with no save point to revert to...

But overall a worthy buy, much better than a lot of indie horror games on the market currently.

The game itself is amazing. With the new updates, the monsters do not wounder around your place for ever, they stay close, but you still can look around. After I escaped the hunter, who I think is the hardest monster to defeat, I couldn't walk. Warning, spoilers alert. When I was moving the crane for the liferaft, I heard him climb up the side of the ship. I screamed and ran. Luckily, I managed to escape. I recomend the game to players ho want themselfs to get REALLY scared.
