UNSORTED HORROR is a collection of 5 short first-person horror games, that revolve around detailed machinery in a dark dystopian setting. The majority of the games have a playtime of roughly 10-15 minutes and can be played through in one sitting. Choose a CD case, read the backside, and go on a small adventure.


1. Tartarus Engine - A group of plucky technicians exploit an ancient machine's seemingly untapped vulnerability.
2. The Other Side - Operate a jury-rigged drill to secretly escape a corrupt bunker. 
3. Control Room Alpha - Pull data from a nest of spiders.
4. Carbon Steel - Perform hazardous research in an abandoned facility.
5. Concrete Tremor - A game revolving around plastic explosives and soviet apartment buildings.


The majority of the content in the collection is comprised of previously released games, that some players may already be familiar with. "Tartarus Engine" was developed as an exclusive for the collection, with the main goal of the collection being a Steam release of some of my better-received experiments, bundled into a neat little launcher.

I hope you enjoy the new game "Tartarus Engine", and thank you for playing.

Tartarus Engine is my favorite game from this collection. I was really curious about what happened to the three guys, but as expected, the game ends on a cliffhanger. Nonetheless, it was a fun experience!

The game's world feels so alive. with NPCs going about their lives and reacting to the player's actions.

I've never encountered a game with such deep and meaningful side quests. each one feels like a mini-adventure in itself.

The attention to detail in the game world is incredible. with each location feeling like it has its own history and story to tell.

The game's story is so engaging. with twists and turns that keep me guessing until the very end.

The art style is so charming and really adds to the overall experience.

The character designs in this game are so creative and imaginative. I love seeing what new characters I'll meet next.

The community around this game is so welcoming and supportive. it really enhances the experience.

The attention to detail in the game world is incredible. with each location feeling like it has its own history and story to tell.

I'm constantly amazed by the creativity and originality of this game.

I love the sense of freedom this game gives me. allowing me to tackle challenges in my own way.

The in-game lore is so fascinating. I find myself reading every book and note I come across.

The game's sound effects are so satisfying. from the clang of a sword to the roar of a dragon.

the plot twists for such short games is wild

loved the the feeling of being slightly uncomfortable at all times

Outstanding collection of short horror games. Intro song, when you are selecting tapes, is perfect to set the right mood. Totally loving the aspect that it does feel like each game exists in the same universe.

I previously completed 4 out of 5 games from this bundle and was excited to play "Tartarus Engine", which is exclusive to this set. So far, that was one of the craziest experiences. The Tartarus ending was mind-blowing, very trippy and gave a doze of existential dread. Consciousness is definitely not something to play around with. And that's pretty much where our society is going.

High-tier production on all games. Well done, Mike.

P.S. There's an error preventing installing the game through the itch.io app: "Cannot read property build or undefined".

loved it!

The puzzles are challenging but fair. making solving them incredibly satisfying.


The last part! Very fun short mini games.

WHAT an experience!! These are some of the best indie psychological horrors I've played in years. You've got a LOT of talent with atmosphere. I played the entire collection, one-by-one, and I had an absolute blast in this video.

You made an amazing experience. I hope if you watch you enjoy my commentary. I can't wait to play more of your games!

Finally played Carbon Steel and oh boy did it take me some time but here it is also good game ∞/10 would put something to sleep and extract its essence again🗿 

This is the second game that I played in this "Experience"
and I hate it 11\10 would hit my balls with a hammer again :D 

Made a video on this and second part out tomorrow! I must say even when I got confused by mechanics of the gameplay - I still had fun figuring it out. Thanks for making these short games :)

This is probably going to be a long review, but this collection deserves it.

Every single one of these games were incredibly original, creative and raw! the intro reminded me so much of Play Station 2, and i loved it.

These games go on topics like war, human experimentation, time loops, and much more. The mechanics are original and tricky (a little bit hard to understand, but once you get the hang of it, it even becomes fun to replay). With little to no dialogue, you managed to create amazing storylines. The only thing i didn't like is how short these games are!

You are definitely going to make it big one day, please keep up the good work! 

Why it isn't in steam anymore?

A game using the same mechanics like V/H/S, my cup of tea

nice game

Awesome game and I'm going to be making more vids on it soon 11/10

Fantastic collection of horror games Mike. I thought Concrete tremor was a bit weak, but the rest were very solid. Tense and immersive!

i had already played concrete tremors but in this video i played the other side which is just as great as your other games. I love the style of your games I cant wait to play more

great mix of games! Can't wait for more from you!

This game was so, so cool! I really liked playing through this compilation of games, my favourite being 'Control Room Alpha'! 

Once again you have absolutely nailed it in creating unsettling scenarios that have the player desperately trying to figure out what to do in order to survive. I had played a couple of these separately but hadn't played either Carbon Steel nor Tartarus Engine and I loved both. Carbon Steel and Concrete Tremor are probably my favorites out the games that I've played from you. Definitely gonna be playing the other games you've made because your style is very unique and you never fail to make it an interesting (and disturbing) experience.

Great Job again
