Hello there! How are you? How's your 2022 so far? 😎
From here, we have a few things to tell you...
As we mentioned you in our last post, this year we reached an entire decade since we started making games as an independent team in Saibot Studios. But it was just now that we actually make something special to celebrate it. Check out the special video!
https://youtu.be/S4-E40ce_Oo
Together with this video, we built and launched a collection with all our published games, including: the Doorways saga, Hellbound and The Black Heart 😈
> LINK TO BUNDLE <
Buying the games from the bundle, gives you a 15% of discount on all the titles. And if you already have one or more of the games included in the package, it will discount you the titles you're missing without needing to buy the entire bundle 👌
TENEBRIS SOMNIA
On the other hand, we receently announced our new creation: Tenebris Somnia. This is a very unique title by the great Andrés Borghi, creator of The Black Heart 🖤
We're developing this project Andrés and I (Tobías Rusjan), together with a great team of artists. You can read more about it and the dev team in this other post we did the past week.
If you like the concept of the game, don't forget to add it to your Wishlists. We're aiming to have it ready during 2023 👍

OUT OF BOUNDS
In the mean time, I keep working on my little jam game Out of Bounds, a rare title with action, shooting and puzzles. We released a demo in June and it's still available to check directly from the store page:
My idea is finish the full game for the end of the year. So play the demo and add it to your wishlist if you liked it! 🙌

HELLBOUND... HELLBOUND?
This month we received the great news from our (now) former publishers that they're giving us back the IP of Hellbound 🤯
What does this mean?
Finally, we at Saibot Studios are going to start receiving sales from Hellbound on Steam. Since the release of 2020, all the sales went to the publisher because that was what we stablished: they recoup their investment first, and then we split; but we never reached that last step because they never recoup their part with the sales we had.
But now after two years from the release, they're giving us back the game so we can atleast see some of the sales. Also, we got back the full rights of the project to take any desision we want from now on 🔥
In March of this year there was the Best of Boomer Shooters Bundle, the first collection of Humble Bundle focused on retro FPSs. Hellbound had the honour to be included in that package, becoming the first argentinian game in participate in the iconic Humble Bundle:
https://youtu.be/ndqIlyYFVJM
Both the sales from this collection and also the sales from now on (September of 2022) at Steam are going to us at Saibot. Yes, finally!
But unfortunately, this aren't earnings for us yet, since we still need to recoup all we put to create the Hellbound: Survival Mode in 2016-2018.
So the future of Hellbound is still uncertain... The good thing is that everything has started looking brighter now, we'll see how things turn for our Hellgore in the next months 🤞
That would be all for now, people. Hope we have some more news for you soon, follow us in our networks to stay updated:

🎂 10 YEARS OF SAIBOT! 🎉
Hello, people! How are you? How did you started 2022? 🤓 In a day like today, but from 2012, we officially started a crazy adventure called Saibot that continues to date. Actually, the very begginning was in 2011 with the conceptualization and prototype of what ended up being our
Hello, people! How are you? How did you started 2022? 🤓
In a day like today, but from 2012, we officially started a crazy adventure called Saibot that continues to date.
Actually, the very begginning was in 2011 with the conceptualization and prototype of what ended up being our first title Doorways (read more).
But it wasn't until March of 2012 that, after I partened with my Uncle and friend Ivan Rusjan, we finally started working as a team. We built the first Saibot "office", which was actually my room along side the bed and at my Mom's department, and we used some old tables as desks that my Grandma gave us ❤️
And from then, a lot of enechdotes and experiences started hapenning. With tons of fails and drop downs, but also with some wins, we were able to keep going to date doing what we love the most: creating our own games and delivering them all over the world 🌎
So I decided to take some time to build and share with you a quick recap of some of the main milestones we have achieved together with you during the last 10 years of Saibot...
2012: The Origin

Hello, people. How are you? It's been awhile.
Tobias Rusjan here from Doorways, Hellbound and Saibot.
I wanted to let you know about the projects in which we're currently working at Saibot Studios. Let's start with the one next to release...
THE BLACK HEART (OCT 2021)
The game The Black Heart, created in its majority by Andrés Borghi, a very talented multimedia artist with whom we had the pleasure to work with for promotional videos of Doorways and Hellbound.
The past year we joined forces with Andres to publish his masterpiece on Steam. We started with Early Access, we kept improving the game and we finally got a definitive version ready to launch 🙌
The full game release is next Thursday: October 21. IN LESS THAN A WEEK!
So go to the store page and take a look. And if you like it, add the game to your Wishlist:
https://store.steampowered.com/app/1431780/The_Black_Heart/
By the way, the new cover for The Black Heart was made by one of the main artists of Hellbound: the great Fernando Muzzio
And the music for the release version is going to be remastered by the sound especialist of Doorways and Hellbound: David Levill
OUT OF BOUNDS (EARLY 2022)
On my side, during August I participated in the Unreal Megajam 2021, and I managed to create a little full game on my own in just 7 days 🤯
You can play that version for free on Itchio; but since I really liked the results, I decided to keep working on this project and to invite another great former-Saibot so we can get the game to the next level: the master of art Viktor Ahmed
The idea is to keep improving it for a couple of months and release a new version during early 2022. So if you like it, add it to your Wishlist as well!

ARRAN: THE BOOK OF HEROES (APRIL 2022)
And outside Saibot, our friends and coleagues who helped us in the past with our games created together Pal'Sur Studios. They are working on an action RPG that looks and plays spectacular 👌
I had the luck to play directly with the creators. So I can really recommend you to add it to your wishlist as well, without a doubt:

Hey everybody! How are you doing? 😷
We're doing very well, entirely working in Hellbound as always. But this time and due to the quarantine established here in Argentina because of COVID 19, every one of us is working from home 😎
Even though the project originally started with all of us working from distance, during the last year and a half some of us have been sharing the same working place.
We started at the old Saibot office located in Caballito (Capital Federal of Buenos Aires), and most recently we moved to Vicente López (province of Buenos Aires).
So we had to set up some stuff to get back to this remote working thing, but it's actually doing pretty well so far 👌
Below you can find us in our "caves"...
Juan "Juancho" Caratino
Tobías "Toba" Rusjan
Fernando "Fercho" Muzzio
David "Deibit" Levill
Victor "Vik" Ahmed
But we want to take this opportunity to tell you about the progress of the Campaign Mode of Hellbound. Today we have:

VISUALS: 75% of the levels now have final visuals
GAMEPLAY: 90% of the mechanics for the levels are currently working
AUDIO: The music for the entirely game has been created, it only needs some new masters and final touches
Also, we continue working on the tombs for The Heroes' Cemetery. Soon enough there will be solid news on this too 💀
We're aiming to have a release for mid-late of this 2020. So we'll see how things go...
In the mid time, don't forget to add the game to your wishlist!

And now, we want to hear from you. How is this virus thing influencing you? Have you been playing the new DOOM Eternal? What are your thoughts?
Let us know in the comments below, we always love reading them 🤓
