Here we go again, you've got a week to check out a bunch of games having their first or updated demos now in Steam Next Fest - October 2025.
Many demos will only be up for this event, but plenty will keep their demo up longer too. More demos than any one person can handle! The official trailer provided by Valve is below:

I've already been highlighting a number of games with demos so be sure to look at our demo tag for previous stuff. All as part of our regular programming, and no doubt more demos will get a highlight as the event goes on, depending on what I end up liking the look of.
Just to get you going for now here's a small list of stuff I personally thought were interesting in no particular order:
The event runs through until October 20th at 10 am PST / 5 pm UTC. See the full event on the Steam store.
Be sure to leave a comment and let us know what you're checking out!

Marvel Cosmic Invasion [External Link]
There's a article a while back, but for those who missed it, it's basically beat'em up from developers of Shredders Revenge. Character are bit different and you get to switch between two of them during the levels. All the basic hitting, grabbing and special moves are there. There's even flying characters, though I didn't get landing in my muscle memory as I always tried pushing downwards direction, but it's apparently A button.
Monsters are Coming! Rock & Road [External Link]
This one had article also a while ago. Basically it's bit similar to Ball X Pit, but without the balls. It has moving city that attacks enemies and you can build with level ups. Levels also have resources you can gather, though it's always compromise between defending the city and gathering resources. Luckily city can be enhanced with resource generation, so you don't always have to risk yourself and the city.
I guess it would be more fun, if Ball X Pit wouldn't exist. Also the music in the demo is bit repetitive.
side note: something is super wrong with the steam desktop app for the next fest home page. At least for me. The top recommendations for me are "parkour time attack anime third person" games. I have absolutely zero interest in that whatsoever, and have exactly 0 games in my library with those tags.
Then moving down, the next recommended category is "minigames games" (terrible recommendation) and the next recommended category after that is "soundtrack games" (terrible recommendation) and then it goes to "all titles".
It's like they swapped my recommendation profile for a total stranger?

That's odd. I have space sim and openworld survival craft games, which would make sense from No Mans Sky perspective.
Though for me, finding unsuitable game categories is somewhat hard. I probably have at least one game for large number of genres.
Best one first:
Star Trek: Voyager - Across the Unknown [External Link]
I'm not sure if this is actually part of the fest, but as demo is available right now, it doesn't matter that much.
While not perfect, having possibility to diverge a bit from what happens in TV series is fun. And resource management and base building is fun enough too. Space battles seem to be bit too simplistic though in practice. Though it still could be even more fun with voice acting from original cast and with original music.
There was article a while back if you want to find more discussion about it.
Stellar Archipelago [External Link]
Steam though I like openworld survival craft games. And Stellar Archipelago does have little bit of charm with practically building stuff on a small asteroid. But problem is that there the fun ends. It's way too basic, even when the premise is kind of cool.
XenoHaven [External Link]
My Japanese is not good enough to play this. Store page claims having English as option, but couldn't understand the menus enough to find where to enable it. Maybe they could just modify the store page a bit to advertise it as Japanese learning game.
But if actually understand Japanese, you get to enslave monsters and run cafes. Or something.
debris [External Link]
This should be drone building and asteroid mining simulator. It's just bit convoluted with barely any tutorial. If you actually try to play it, the top left corner thing can gather resources if you browse through the options. That actually should make it possible to launch a drone. What happened me though was the the freeplay dialog refused to close. So I gave up.
Trade Anchor [External Link]
Space trading game, what's not to like. Though intro wasn't very promising as it was very laggy. Problem is though that there doesn't seem to be easy way to scroll the screen. There might be ways to work around it, but they're bit too inconsistent.
But basically you fly between star systems and buy resources. Then you try to find systems that wants the resource and is willing to pay higher price. I didn't saw any indications how much profit or loss you are making with the sale, so you need to rely on your memory. Or make notes.
Beneath [External Link]
Beneath is Cthulhu inspired horror FPS. Demo has less Lovecraft though, but trailer has stronger vibe. Practically it seems to be some mix between Doom 3 and Half-Life. I guess worst thing is that it really doesn't do anything that hasn't been done before, but towards the end there's bit more sense of purpose. There's even more hints about the storyline.
Kind of mixed thing is that there's no manual saving. If things get too difficult, it gets frustrating. But when the balance is just about right, it's more tense than it would be possible with a save anywhere system.
Kind of almost wishlist material. Don't know though if I would have enough patience to play it all the way through. Though at least there's easier difficulty level available.
The Last Caretaker [External Link]
The Last Caretaker is openworld survival crafting game, but it does things bit differently. In the demo you do lot of door opening and connecting cables. And draining batteries. Didn't get a chance to punch a tree at all. Based on the store page, it's vaguely similar to Raft if it had robot as player character.
Store page hints also that there's more. For example small things like saving humanity.
While the demo was fun, there were some issues though. The recycler seems to be quite poorly introduced. And it's pretty essential in advancing the demo. Had to read the discussions to figure out where it could be.
Earth Must Die [External Link]
There's recent article about this. But just in case you missed it, it's traditional point & click adventure. It goes bit into adult humor territory as gore and sex, though in quite cartoony way. Puzzles in the demo are on the easier side. Kind of almost wishlist territory.
In The Black [External Link]
Basically it's space combat simulator with newtonian physics simulation. Tutorials didn't lean on that properly, but at least acceleration was covered in detail. Though I already know from Rings of Saturn that speed kills...
Maybe I'll try more of it later. My rest of the evening went to the next one...
Powerwash Simulator 2 [External Link]
Haven't played the first one. If you have missed the game entirely, it's more or less what it says in the title. The second one has apparently more content and multi stage levels among other things. Small annoyances come from hard to reach places, but ultimately there's nothing that crouching and jumping can't solve.
Once you get bit of routine into things, your mind might start wander somewhere else while the grime slowly vanishes.
This one actually goes into the wishlist. Especially if the price is not too steep, could buy it right away when it releases.
Truckful [External Link]
There's recent article about this one.
If you don't feel like reading it, it's kind of roadtrip simulator with physics based cargo and some horror elements. Takes a moment to figure out what logic the controls follow and get them into muscle memory. Plays bit like side scroller due to the camera angle. Which people complain about.
Kind of has charm, but I'm not sure if I would have patience for it, unless the story gets more interesting later in the game.
Adorable Adventures [External Link]
Play as a boar. Nice narration and sense of smell is integrated nicely into the game. Bit on the cozier side, though you can race a bit. Downside is that there are some places where you can fall through level and the game has no handling for that at all. So remember to save when you make progress.
Bit odd one out in the cozy genre due the graphical fidelity and system requirements. But it does look pretty.
Winnie's Hole [External Link]
There's also recent article about this one.
If you don't want to read more detailed description from the article, it's kind of body horror deck builder with Tetris like elements. You play as virus inside Winnie the Pooh, which explains why the story deviates quite lot from the children books.
I guess it's fun enough. Could see myself playing it if I wouldn't have anything else to play. Which is very unlikely to happen.
Effulgence RPG [External Link]
There's recent article about this.
The user interface is confusing at first. But at least the ASCII art is is gorgeus. The actual gameplay is RPG battles with some resource management.
Got mildly frustrated and didn't feel like playing all the way through. I guess the resource management part felt bit unfair, but that could have been skill issue.
Lifted [External Link]
There's recent article about this one. Certainly cinematic puzzle platformer describes this one nicely. It's aiming for Indiana Jones vibe, though none of the main characters are directly lifted from it. Platforming requires some precision. Though there's some difficulty settings and one of the settings makes platforming easier. I guess with default settings, it can be bit confusing where you need to go, especially towards end of the demo. The final action piece doesn't feel as snappy as it could be.
Goes into almost wishlist territory. But still maybe if I have a cinematic platformer itch...
Dogpile [External Link]
There's also recent https://www.gamingonlinux.com/2025/10/merge-dogs-to-make-bigger-dogs-in-the-roguelike-deckbuilder-dogpile/ about this one. This one is basically roguelite Suika clone and market is not flooded with those...
If you have missed whole Suika craze, it's basically game with you merge balls to make bigger balls with added difficulty of balls bouncing around. Of course in Dogpile balls are replaced by dogs. But as it's rogue-lite, there's all kinds of upgrade systems and a shop.
Even when I'm not exactly a dog person, it's fun. Once you figure out what to do, the demo is actually winnable. Interesting to see if they make things more difficult in the final game. At least if they add more things, getting just the right synergies will be less likely.
Have to see how this develops. As cat person, I'm bit hesitant to add it my wishlist, but it is tempting.
Dream Garden [External Link]
It's one of those cozy build a diorama games. You can modify terrain and add items.
I can see somebody else playing this, but I know from experience that games like this don't hold my attention long.
Game About Feeding A Black Hole [External Link]
Incremental game about feeding asteroids to a black hole. Once you actually make some progress in the upgrades, things get lot more satisfying.
Maybe if it's cheap enough, though few surprise twists could be good, otherwise it gets too repetitive.
Megabonk [External Link]
This one has recent article. Just had to try why it's so popular. And I can see why. While it's heavily inspired by Vampire Survivors, kind of deranged humor and 3D makes it it's own thing. Some of the enemies are quite bonkers.
Wishlist material.
Also small In The Black [External Link] update. The tutorial mission shows how hard it is to hit to a moving target. Luckily the second ship has missiles. Certainly requires some practice, but I'm not sure how much plot there's going to be. I guess I'll have to keep trying it some more.
