Abiotic Factor The Cosmic Companions Update Patch Notes (4th May 2026)
Abiotic Factor's biggest update yet adds a full chemistry system, revamped pets, and a brand new area to explore.
Over 100 new items in a single update is a number that demands attention, and Deep Field Games has delivered exactly that with The Cosmic Companions Update, live now for Abiotic Factor.
The headliners are the new chemistry system and a complete Pets 2.0 overhaul. Chemistry introduces Distillation and Chemistry Benches that let you brew Tinctures, Coatings, and Flasks, buffs for your body, weird effects for your weapons, and throwable concoctions for healing allies or punishing enemies. It's the kind of deep crafting layer survival fans have been asking for. On the pet side, you can now pick up any pet with a free hotbar slot, tame Peccaries to fight alongside you, and feed pets to trigger mutations that transform them into entirely new creature types. The new Companion Collar slot also keeps your pet in a downed state rather than dead if it takes lethal damage, which is a smart quality-of-life call for anyone who's lost a beloved creature to a bad fight.
There's also a new portal world, the Alpen Signal Observatorium, accessible through the western waterways of the Hydroplant, plus new blunt weapons, a fan-powered office chair vehicle, and a mop. Yes, a mop. Here's the full breakdown.
Full Patch Notes
[color=#33FFDD]Greetings, esteemed colleagues!
Welcome to the most scientific Abiotic Factor update yet! Prime your science-selves for the all-new chemistry system, new pet companionship, extraordinary pet evolutions, an anomalous Alpen Adventure, new weapons, tools, vehicles, furniture and more. Let’s dive in!
Dev Vlog
Familiarize yourself with the full dimensions of this update via our rigorously scientific vlog, featuring Zag, Criss and a fresh addition to the Abiotic Factor design team!
Voices of the Void
Just across the range from Voussoir lay the Dunkeltaler Forest, home of the mysterious Alpen Signal Observatorium. To access this new portal world, explore the western waterways of the Hydroplant, where Dr. Newman noted some unusual perforation readings. Perhaps you can investigate the source of the signal…
Pets 2.0
Welcome to Pets 2.0 - and it’s a whole new world. The pet system just got seriously enhanced, with a huge boost to your roster of potential friends and their abilities: feed them, farm them, tame them, mutate them, and enlist them as accomplices in your next adventure.
With the Companion Pet Slot, pets placed in this slot will be equipped with a stylish and functional companion collar that will keep them stable in a “downed” state if they take what would otherwise be lethal damage. This way your companion can aid you out in the field while you face down the myriad dangers of Cascade, and you don’t have to fret about it being in mortal danger!
Tameable Peccary
New advances in chemistry have enabled Peccary Taming! Once tamed, these loyal beasts will fight by your side, and certain variants will even produce harvestable resources on a semi-regular basis.
Picking Up Pets
All pets can now be picked up so long as you have a free hotbar slot, not just IS-0128-A. You can pet them while holding them, and this means that anywhere a scientist can go a pet can go too. That includes those hefty peccaries! Lift with your knees!
Feeding pets may result in various anomalous effects, including permanently mutating the pet into a different type. Experiment away!
Chemistry System
You asked for a deep and wide Chemistry system that rewards experimentation and inquiry…. The Distillation Bench and the Chemistry Bench will now enable chemically-bound scientists to distill items into Distillations and then turn them into magnificent Concoctions, which can be created in three distinct types.
Investigate Tinctures that buff your science body in myriad strange and interesting ways - go fast, go big, go berserk, and that’s just for starters.
Explore Coatings that grant your weapons an array of weird, wonderful and wicked extra effects - confirm that scientific progress does indeed go boink… sometimes.
Concoct dangerous Flasks that deliver unique effects to deliver rapid aid to allies, intense harm to enemies, or just for pranking your colleagues! - discover just how far you can push your potion-making.
Chemistry Cosmetics
There’s a handful of new cosmetics you can equip yourself with - some are unlocked by default, and some require a little bit of investigation. Except for the labcoat - that’s part of the crossover nonsense. Ahh, you’ll figure it all out. You always have before.
To Be Blunt With You
For anyone who likes to “research” their way through the facility using Blunt melee weapons, we’ve dropped a few new “field study” devices to “perform research” on “the bodies and heads and faces” of your foes. You’ll really enjoy “hitting aliens with big swinging objects.”
… If you get our drift.
Chairs to the People!
Power Chairs, that is. GATE didn’t add ramps all around the Cascade facility because we like walking on inclined surfaces! They added them for accessibility, of course! Did these grand architects expect that most of that accessibility would one day allow traversal with high-powered fans strapped to office chairs?
Well, no, the answer is no. I can’t believe you would think the answer might be yes.
Behold, the M.O.P. 9000!
Desperately need to clean up blood, vomit, and other unsavory slime? Well, the M.O.P. 9000 is exactly what you need. Yes, it does exactly what you want. Just make sure you have a barrel of water nearby to keep your M.O.P. in tip-top shape!
And the list goes on!
Cosmic Companions is full to the brim with over 100 new items! That means new recipes, loads of new furniture, inventions, QOL, and bug fixes galore. This is what happens when you leave us alone in the lab with little-to-no oversight whatsoever. Looking for the full run-down on everything we’ve added?
