Serum

Bringing the creatures to life



Hey survivors! As we already mentioned on our Discord channel, we are in the process of switching from UE4 to UE5 while working on Serum. This will help us deliver a quality survival experience with top-tier graphics, and we can’t wait to showcase some of the fantastic stuff we made so far.

In previous devlogs, we have shown you one of the creatures you will encounter in the game – The Mist Wolf. You could also see them in the teasers. Now, it’s time to reveal the upgraded version. This particular mutation is called the Alpha Mist Wolf, and as you can see, he’s not one to be messed with.



Below, you can also find some of the original concept art that the creature is based on. In Serum, players will cross paths with a multitude of creatures – each with their own distinctive characteristics and behaviour. We will update you on the progress and show more of them in the future, so stay tuned!

The fauna of this island keeps surprising me



From the first day, I found myself trapped in this strange place, I noticed that some plants carry the valuable Serum that helps me to stay alive. They are not the most sustainable source of this substance, but they provide just enough to get me through the day.

What I discovered during my most recent expedition to the yet-undiscovered parts of the island shook me to the core. I came across a rather sizeable tubular plant that seemed very… alive. I didn’t want to risk advancing towards it and kept observing from a distance.

After a short while, a family of Rotten Rabbits approached the plant as if they wanted to try if it was edible. As soon as they got close enough, the plant exploded, launching its Serum-infused spores into the air. The rabbits fell almost immediately, but I was unsure if they were dead or incapacitated.



I could swear that with each minute, I spotted more and more of these plants as if they were reproducing rapidly. The truth was they were camouflaged well with the forest undergrowth, so I had to be extra careful with each subsequent step.

I decided not to go any further and returned to my shelter. I need to make a plan on how to proceed. I must find a way around the plants if the spores are deadly. And even if they are not, they still might accelerate the mutation or, best case scenario, grant me a new ability. So many unknowns, yet I’m in no hurry to find out.

One thing that really makes me lose sleep is these plants must have grown from other seeds or spores, which means there is potentially a much larger plant somewhere out there. I just hope I won’t cross paths with it.

Time feels different here



I have lost track of how many days I have spent in this cursed forest. The exhaustion is starting to take its toll not just on my body but also on my mind. With each passing night, I feel an inch close to madness.

I have noticed something strange about the creatures outside – they have become more alert – as if they are waiting for an important event to happen. The days are becoming shorter and colder, and my longing for home is getting stronger.

Could this mean it’s that time of the year? If that’s the case, then to whoever finds this note: I wish you Happy Holidays.

A deadly and silent weapon



Day 25

Thanks to my multiple excursions, I managed to find some useful scrap. I was never very good with a bow and arrow, but at least it’s a fairly easy-to-craft weapon. I could build my bow by connecting a few pieces of metal, some gears, and a sturdy and flexible string. All I need now is a little bit of practice. Before venturing any further and facing tougher creatures, I should look around the safehouse for smaller, less dangerous prey.

Day 30

I just had a brilliant idea – or at least it seems like one. If I could place a small container just above the bow handle, I could use it to store different types of Serum and use it to enhance my arrows. I am sure that some varieties of this substance could affect my enemies differently. Maybe this will give me an upper hand against some of the abominations that stand in my way toward freedom.



Day 32

Yes! I have tested my theory, and the serum-soaked arrows proved to be a great help against a pack of Mist Wolves. The damage I can now deal against those creatures is significantly greater than before. Let’s experiment more with different Serum recipes and see if I can move to another area. This one is becoming very scarce in resources.

Happy Halloween, survivors!



Take one fresh foot of a crow, a large centipede, and a handful of seeds from a rotten pumpkin. Mix well into a Serum, apply into your system, and enjoy the ride!

It’s the time for scares and spooky stories, and while ours is still in the making, we can’t stop ourselves from wishing you a very Happy Halloween. Hope this will we be an evening full of frights and treats for you to enjoy.

Stay safe, survivors!

A lucky find

Day 17

I’ve been here long enough to know that I cannot get out of here without harnessing the Serum. Almost every organic being in this land is filled with green fluid, just waiting for me to collect. On one of my recent expeditions, I found a strange blueprint for a contraption that looks like it might help me retrieve the substance from the Rotten Rabbits.



I can still do it by killing the creatures, but I must traverse further after each hunt to find more colonies. Making this device might help me get more Serum from each animal I bring back. I have the traps already, so catching a live specimen should not be a problem. I must look for parts and try my luck.


Day 23

I did it! After building the device and several failed attempts, I finally have a sustainable source of Serum. If I could find more blueprints, I would be able to build bigger contraptions and gather the substance from larger animals. This would be my next step to freedom. No time to waste – I need to keep exploring.

A strange feeling

I know that the only way to survive in this treacherous land is to inject myself with a mysterious substance that somehow shields my body from the hazardous environment. But there’s also something else I’m experiencing with each new shot.



The Serum alters how my body reacts depending on how I mix the ingredients. I still haven’t figured out exactly how this works, but once, I felt a strange increase in my mobility after injecting myself with Serum mixed with a substance that came from the Rotten Rabbit. Or maybe that was just the adrenaline?

I wonder if I can use that to my advantage and increase my chances of ever leaving this cursed place. I need to do some more testing before I am completely sure, but I have a strange feeling that I’m on the right track. The only way to find out is to hunt some more dangerous creatures and create a new mixture. This better be worth the risk!
