A downloadable game for Windows


What are you capable of doing, for the sake of the only native person?

You must – this is a game with elements of survival horror in the first person.

The main character is an ordinary guy who loves video games and social networking. His family is a younger brother.

He is trying to earn money and find a good job to take care of his brother.

In the social network, the main character plays the quest "Hide and Seek", but this time the organizers decided to move the quest to the real world. They indicate the coordinates of the place where the quest item was hidden, the one who finds it first will receive a cash prize. The conditions are simple, come to the designated place and without catching the eyes of other players, find the item. It would seem that it could be easier. But the player does not suspect that he will have to fight for another prize – survival.

- Genre "Survival horror";
- Realistic graphics;
- Plunge into the history of the military base, find out why it became abandoned;
- Open locked doors to find a quest item;
- Listen to the sounds, you are not alone here!

Game was fun, a little buggy but a lot of fun. Items were well placed and I did not feel like I was over exploring. Can’t say there was much of a threat, got the enemy stuck on pallets at the start of the game. Still quite a lot of great scenes, and the just scares worked well.

what happened to the download?

There was an error in the download, the button was removed. Fixed!

This game is awesome! <3
The story is simple, but also brilliant and I love the atmosphere
and the effects. Scared me a few times xD

Surprisingly well thought out as the notes slowly start to make sense as you progress. Checkout my condensed gameplay and watch my heart rate jump to 150 lol


This game made it to my Top moments of 2021

I may have given up in the end, but it was still a SUPER scary and enjoyable experience. Will most likely play again to completion. 

I almost gave up man smh. scary af

This game is great! Next level I tell u.

I would like to collaborate with you on your next projects.

I'm a game writer for various indie studios , and always on the lookout for new challengers.

My role as a writer is to formulate character / narrative driven documents , gaming and character backstories , as well as implementing puzzles and side quests.

I too have completed my first kinetic VN - Axiom Alternative. Available for purchase on STEAM, and very soon will be working on another VN project with a different studio, and Axiom Alternative 2 is currently available on STEAM. I'm up for any challenge, and would like the opportunity to show your studio what writing material I can bring to the table.

I'm currently working on a document for a psychological, horror type game. Maybe we could collab on future gaming projects.

Any questions, feel free to ask.



This was  a pretty cool horror experience. I liked the concept of accepting an anonymous challenge on the internet not really knowing what to expect - it gave off  a "dark web danger" kind of vibe. The jumpscares got me REALLY good. The only critique I have of the game is the story. I understood the gist of it, but what was the significance of the challenge and the quest item? Who (or what) was the thing circling around the building? What are Jupiter's intentions - are they good or evil? I think adding more detail to the story would have enhanced the game a bit. Overall, you did a nice job creating a dark and tense atmosphere and I enjoyed playing this game.

Exclusive content on Steam?

The same version as in steam!

Is there difference between demo verison and full version?

Yes, there is a difference.

game updated again

while the game wasn't exactly challenging the jump scares actually got me which hasn't actually happened in a while. so that was pretty cool.

anyways here's my vid check it out if you feel like it.

This game was FULL of jumpscares and I couldn't be happier! The game length was a good length and the variety of enemies were cool to see. Although only one of them actually chased you, the mediating guy who followed you throughout the gameplay was spooky as freak. This game was a really creepy experience! Keep up the good work!

What a fantastic piece! Above all, I think what I loved about this game most was how gigantic it felt. From the outside, the building was not striking. Once inside, it was an absolute LABYRINTH. No two rooms felt the same, which is a great asset to you as a game developer because it speaks to how you took the time to specifically develop each room and make them unique. Your monsters were creepy and the level of difficulty was at times burdensome (with looking for items) but at no time did the game feel unfair. If I had any constructive feedback to give, I would only say that, as a player, I did not find myself too interested in the story of the facility. I think that's because there is already story enough: as a player, you know why you are there, you find out that you have been tricked, and you know the conditions of your survival (find the quest item and leave). For me, it was hard to care about the story of the facility and the zombies because in no way did learning that story pertain to the game. Yes it explained why there were such horrendous creatures, but it did nothing to help me as a player nor did it change my objective. I just wanted to find what I was looking for and get out. (BUT, that's just me and maybe others feel differently!) Despite this, you should be incredibly proud of what you've created. You've a real talent and I encourage you to keep creating.  Thank you again for the fun experience!

Jumpscares on Jumpscares... Gameplay came out beautiful very fun. Love to see more games from ThinLine like this.

Check out my gameplay

I Really like this game, scare me a lot of times, i made a gameplay of it and i hope you like it

This game was really spooky. But worth a try! Thanks for this experience. 

Whats this assets pack, I seen this used in Summer of '58

Apparently the assets are similar

The gas mask prop and a few others are identical, hoping to find this assets, thanks <3

I would say this game scared me so bad, unlike any other game... the jumpscares are super bad (in a good way) and I would say that the developers did a very good job at this game although the game was very short and sometimes it's confusing on what to find and going into places then coming back not sure what to find I was confused for 40 mins in my whole stream on what I have to find but overall the game was really good because of the jumpscares and made the game lil more spooky and creepy where there are dead bodies and experimenting on people. If you wanna see my highlights of this game I will put the link below :)

I think I will retire undeafeated from this Hide and Seek game. Very tense and spooky game. I really enjoyed it. Keep up the good work! 


I really enjoyed the game however one our two things im confused about, the meds I don't see the point in having because when that thing outside finds you it seems to run faster than you so you can't run away and heal and also whats the point in collecting lighter fluid when your lighter doesn't run out. Also the first time the game saves all of the lighter fluid and meds spawn back in the same place as before once I noticed nothing inside can chase you it wasn't as scary for me.


I'll fix it, thank you!))

update coming?

Да, будет перед релизом в стим! 

Финальный финал

Напишите мне в почту пожалуйста, что хотели бы исправить в игре или добавить. Буду рад это учесть перед выпуском игры в Steam!
