5 Free-to-Play Multiplayer Game Releases to Look Out For (SEP-OCT 2026)

Sometimes gamers don't always have extra funds lying around to buy the newest releases but still crave playing something new when their usual titles grow tiresome. That's what makes free-to-play games so brilliant, even if they don't always end up on par with the more expensive AAA titles. However, it can be tricky finding suitable free-to-play titles that also offer multiplayer features, such as PvP, co-op, or MMO capabilities.

If you're in dire need of a new free-to-play multiplayer game, then there are a few different options in terms of new game releases, free play weekends, and major content updates to keep your eye on throughout the next month. We've rounded up five of the best options, so without further ado, here is a range of different free-to-play games that you can try playing with or against your friends.

Once Human 3.0.5 & Isles of Abyss - September 2

If you're yet to jump into Once Human, then now may just be the perfect time to do so. This free-to-play survival game has been going strong since launch and recently made its way to consoles in August 2026, further expanding its playerbase. Luckily, for those craving a solid open-world survival game, Once Human is now more accessible than ever. Grab your squad, jump on in, and discover everything its post-apocalyptic world has to offer.

The recent 3.0.5 update added a bunch of gameplay refinements, but more importantly, the upcoming Isles of Abyss update will mark the largest content update for the game to date. This makes now a great time to get familiar with the game before new maritime survival features, including underwater environments, ocean exploration, and island bases, go live.

Tyr - September 3

Tyr is a free-to-play multiplayer tank shooter that has rumbled its way into Early Access on Steam at the beginning of September 2026, already proving a strong star with very positive reviews. There is a range of land and hover tanks to take control of, with the ability to personalize them with upgrades and customization through the combination of a tech tree and component slots. Every vehicle also has a unique power that can help you turn the tide of battle in this PvP frenzy.

The game is also rather strategic, with a unique mechanic that only enables enemies to be seen when they are either in range or making enough noise to reveal themselves, which adds a new element to positioning and space control. If you're into strategy-based team battle games, then why not see if the Tyr tanking experience is something you find enjoyable?

Borderlands 4 (Free Play Weekend) - September 11

While not completely free-to-play, Borderlands 4 is having a free weekend from September 11 - September 15, 2026. If you've been curious about the game but on the fence about spending the money, then now is your chance! Why not rally up your friends and enjoy the chaotic gameplay, eye-catching characters, and co-op fun? It won't matter if you're a Borderlands veteran or completely new to the franchise; this free Borderlands 4 weekend is an opportunity for all kinds of looting-shooting fun!

Aniimo - September 16

Aniimo is perhaps the biggest name on this list in terms of a stand-out game. If Palworld has ever caught your eye, then this will very likely be the next big competitor. If you've completed the game and are looking for something new, or perhaps you liked the look of Palworld but weren't able to spend the money, then Aniimo is a new free-to-play alternative releasing on September 16.

The game is rather charming and stunning in terms of visuals and environments; the creature designs are incredibly endearing - and there is even evolution! Aside from that, you can unlock new abilities for your monsters, explore a variety of environments, and interact with other players around the world. You can even play co-op with your friend, taming awesome and adorable monsters together as you progress through the game. Oh, and battles, of course! Best of all, Aniimo is launching almost everywhere you could imagine - PC, PS5, Xbox X/S, and even mobile a week later.

AION 2 - October 6

Last but not least, there's AION 2, a new option for MMO players to sink their teeth into once early October hits. It's a long-awaited sequel to the original Aion and is launching completely free-to-play, with eight playable classes, PvP and PvE combat options, and a massive world to explore with one another.

If you're really eager to try this one out as soon as possible, early access is available starting September 30 for players who purchase a Founder's Pack. This gives them five days of play before the game launches to everyone else, letting them get a head start in the magical world of Atreia and dive in headfirst to discover what secrets it holds.
