Warframe

Warframe is the game on this list I respect more than I actually play, which is its own kind of honest recommendation. The mission-based co-op is genuinely deep, squads matchmake into planetary missions with matched objectives, and crossplay keeps the population healthy even on a platform as small as Switch. I bounced off the onboarding twice before a friend walked me through Warframe builds over a call, and that's the real barrier here. It's free, so the cost of trying isn't the problem. The problem is a wall of systems thrown at you before the game explains why any of them matter. For players willing to push through that first ten hours, there's a genuinely excellent squad-based looter underneath.

Warframe has been running for over a decade and it shows, in a good way. There is an enormous amount of PvE content here, and cross-save plus crossplay across basically every platform, including Xbox, means my group could pick it up on a whim without anyone needing to own a specific console. The onboarding is genuinely rough. New players will spend several hours confused about what a Warframe even is before the game starts making sense. Once it clicks, the mission variety and squad-based combat are excellent, and it costs nothing to try. For a group willing to push through the slow start, it is one of the best free co-op options on Xbox.

Warframe's early hours are famously rough. I nearly bounced off it myself before the movement clicked, wall-running into a bullet-jump combo that feels good even before you understand what it does. Push past the confusing opening few hours and the game turns into one of the deepest buildcraft systems in any shooter, with hundreds of Warframes and weapons to mix for four-player co-op missions. It's a bigger time investment than anything else on this list except maybe Destiny 2, and the onboarding friction is genuinely off-putting for newcomers. Missions themselves run short once you're past that wall, some barely twenty minutes, which makes it easier to slot into a spare hour than the raid-length commitments higher up this list.

Warframe is the kind of free download I tell people to be careful with, because what looks like a quick sci-fi shooter on the surface is actually one of the deepest time investments on this list. I installed it out of curiosity one weekend expecting an hour of dabbling and ended up building a loadout at 1 AM instead. The third-person shooting is solid rather than spectacular on its own, all mobility and space-ninja acrobatics, but the mission structure and buildcrafting give it staying power most premium shooters can't match. It's genuinely free, no paywalled campaign hiding behind it. The steep learning curve up front means casual players may bounce before the good stuff kicks in.

Warframe has a reputation problem: the first three hours are rough. The game drops you into a ship full of menus and a movement system that takes actual practice to feel good. Push through that. On the other side is one of the most generous free games on any platform. Every Warframe, every weapon, every major update is earnable through play. No paywalled content, no power locked behind spending. I gravitate toward the mobility, which rewards the same instinct that makes me enjoy traversal in games like Ghost of Tsushima, except here you are wall-running at speed in zero gravity. The onboarding is the only real barrier.

Warframe is one of those games I kept bouncing off before it clicked. The first hour is genuinely rough. Too many menus, too many currencies, not enough explanation of why any of it matters. Push past that, ideally with someone who has been playing for a while, and you find one of the most generous free-to-play games ever made. Hundreds of hours of co-op content, nothing essential locked behind a paywall, and a live game that has been growing for over a decade. The missions run about ten to twenty minutes, which suits evenings where you want a few runs without committing to a full session. Worth the patience.

Warframe is genuinely hard to summarise in a sentence, which is part of why it does not get recommended as often as it should. Free to play, over ten years old, constantly updated, and deeper than most paid games on this list. Crossplay matters here because grouping in a progression-heavy co-op game used to mean you were stuck with whoever happened to be on the same platform. That constraint is gone. The honest caveat is the opening hours, which remain confusing in a way that even veterans struggle to explain to new players. Get past the first few hours and you will find one of the most fluid movement systems in any shooter, attached to years of content.

Warframe is free, runs across every major platform, and has been adding co-op PvE content for over a decade. That sounds like a press release, but the practical reality is this: I spent a weekend trying to get back into it after a long break, and the onboarding is still genuinely rough. The game assumes you remember things you have not thought about in two years. Push through that wall, or start with a friend who knows the systems, and you have access to one of the deepest co-op ecosystems on any platform. For groups willing to invest the time, the long-term value is almost unmatched on this list.

Warframe is free, has more content than almost any game on this list, and cross-platform squads now work across all major ecosystems. By those metrics alone it probably deserves a top-ten spot. The reason it did not make it is the onboarding, which is genuinely one of the most demanding of any live-service game. The first ten hours involve learning systems that the game barely explains, finding gear that feels overwhelmingly complex to evaluate, and wondering whether the early missions represent the actual game. They do not. Around hour fifteen it clicks. For groups prepared to push through that together, Warframe has years of content waiting. For everyone else, start elsewhere on this list and come back to it.

Warframe has hundreds of hours of co-op content if you can get past the front door, which is a big if. The onboarding systems are dense in a way that does not suit handheld habits, and while controller support is adequate, the menus are not built for a small screen. Once you are past the early friction the mission loop is fast, social, and replayable for years. It is free, which helps. But as a Steam Deck multiplayer first recommendation it sits low because the investment required before it becomes enjoyable is higher than most people playing on a handheld will tolerate.

Warframe is arguably the best free-to-play action game ever made in terms of sheer content volume and monetisation fairness. The reason it is here rather than in the top ten is honest: it is the heaviest game on this page, the install size is large, and truly weak machines will need aggressive settings adjustments to get acceptable performance. If your laptop has a dedicated GPU, even a modest one, Warframe is worth every megabyte. On integrated graphics it is playable but not the smooth experience you get from the games ranked above it. Go in with realistic expectations about what your hardware can do, and it will probably still surprise you.

I came to Warframe expecting to bounce off it the way I bounced off Diablo IV. Instead I was still running missions two weeks later, trying to unlock my third Warframe without spending anything. That is the thing people do not believe until they try it: the free content here is not a tease. It is the game. Fast movement, tight shooting, melee that actually feels satisfying on a controller, all of it lands correctly on Steam Deck without fighting you. Verified status, reliable performance, hundreds of hours of PvE content before a purchase even enters your head. Nothing else on this list combines all of that as cleanly.

Warframe is what I wish Diablo IV had been for me. I started it, got lost in the onboarding, and almost quit in the first two hours. Then a friend who had 400 hours in it sat down and explained three things, which Warframe to chase first, which mission type actually teaches movement, and why the currency system is less predatory than it looks. After that session I was in for weeks. The amount of content available without spending anything is genuinely extraordinary. The onboarding is still a real problem for solo players on console, but if you push through or find someone to show you the ropes, there is nothing else like it for free co-op depth on PS5.

Free-to-play games that are genuinely not predatory about it are rarer than they should be. Warframe is one of them. The monetisation is cosmetic-focused, the content is enormous, and the co-op missions have enough variety that sessions with a regular group stay interesting well past the point where most games would have run out of ideas. The real obstacle is the first ten hours. Nothing is explained well, the menus are intimidating, and the gap between what a veteran player understands and what a new player can figure out independently is wide. I would not recommend starting it alone. Start it with someone who already plays, or find a guide before you touch the star chart. Once the movement system clicks and you start building frames you actually enjoy, it becomes very hard to stop.

Warframe is a game I kept bouncing off for years before it finally clicked. The onboarding is a known problem: too many systems, too many currencies, too little explanation. Once you get past that, the co-op loop is legitimately excellent. Missions run fast, build variety is enormous, and crossplay means my PC friends and I can run missions together without any of us switching platforms. It is free, which removes a meaningful barrier for anyone trying to get a group started. I would not recommend it to someone who wants to be up and running in an hour, but for groups willing to invest a few sessions into understanding the systems, the payoff is real.

I have a rule about free games: if it asks me to pay before it has earned my attention, I uninstall. Warframe never triggered that rule. I dropped in for what I thought would be an evening and ended up three weeks deep into a movement system that makes most paid action games feel stiff. The PvE depth here is genuinely extraordinary for something that costs nothing to start. New players will feel overwhelmed in the first hour, possibly the first three. Push through it. Once the parkour clicks and you start building frames around specific playstyles, this becomes one of the best action games on PC, free or otherwise.

Warframe is free to play, has been actively updated for over a decade, supports crossplay and cross-save, and has more content than most premium games charge three times for. The co-op mission structure, running tilesets with a squad, building warframe loadouts, crafting gear through play, has a rhythm that pulls you back repeatedly. The catch is upfront complexity. The game does a poor job explaining its systems early on, and new players often bounce off the first few hours without guidance. I'd recommend looking up a beginner guide before jumping in. Once it clicks, though, it's one of the best free multiplayer experiences on PS5 by a wide margin.

Warframe sits at number one because no other free-to-play game on PS5 comes close to its combination of co-op depth and genuine zero-cost access. After a quick 15-minute tutorial, you're in squads running missions, bounties, and eventually the Railjack space combat mode where up to four players take coordinated crew roles. What makes it remarkable is the trading economy — players exchange premium currency between each other, meaning every Warframe and almost every weapon is obtainable without spending real money if you're willing to grind. The onboarding is notoriously dense, and the early hours can feel chaotic. But for a long-term co-op group, nothing else on this list has this much content waiting for free.

Warframe is the only game on this list where PS5 players can co-op with friends on Switch, Xbox, and PC simultaneously — and it's free. That crossplay breadth, combined with full cross-save via a linked Warframe account, makes it the most flexible option here for groups spread across multiple platforms. I'd rank it first if the onboarding weren't so brutal. Dropping new players into Warframe cold is rough, and cross-platform groups who can't sit together in the same room to figure it out will feel that friction hard. Push through the first few hours, though, and there are hundreds of hours of co-op waiting on the other side.

Warframe is free, cross-play capable, and has more PvE content than most games on this list combined. So why is it an honorable mention? The new-player experience is genuinely rough—the progression systems are layered in ways that take weeks to understand, and without a veteran player in your group to explain what you should actually be doing, the early hours feel directionless. Late-game content also trends toward solo play. That said, for a group with at least one experienced Warframe player, the co-op missions and endless progression loop offer hundreds of hours at zero cost. Hard to dismiss entirely.

Warframe delivers a huge amount of free co-op content with deep build crafting and smooth cross-play centered on 4-player teams. Space ninjas clear missions with abilities that naturally create roles like crowd control and support, giving runs real structure. Full cross-platform play means Switch players join the entire community. The steep learning curve and dense menus can intimidate, but groups gain years of shared goals.

Warframe ranks high for blending fluid acrobatic combat with deep mod-based RPG progression and years of free story updates. Players pilot powerful suits through co-op missions, collecting and customizing dozens of warframes and weapons for real build variety. Story quests add emotional weight, and free players can access everything important through trading. Ideal for co-op fans who enjoy long-term character collection and tinkering.

Warframe is a fast looter-shooter with three open-world landscapes for freeform roaming alongside its core instanced missions. It shines for fair monetization and constant updates, letting you improve frames over time. It narrowly misses because most gameplay is mission-based rather than open-world exploration. Still, if you enjoy tight combat with occasional open zones to breathe and explore, it's a great free option.

Warframe is a sprawling co-op looter where sliding, shooting, and abilities blend into fast stylish missions across a mountain of content. It earns its place for unmatched variety and a fair model that lets you grind for almost everything. The gunplay is solid, buildcraft is deep, and regular updates keep veterans busy. It's a hybrid leaning on melee and powers as much as pure gun skill, best for PvE players chasing long-term progression.

Warframe shines as a cooperative looter-shooter with massive depth, constant events, and true crossplay that keeps squads together across platforms. Space ninjas tear through missions chasing new builds in smooth, fast action. It offers enormous free content from star chart progression to open worlds and cinematic quests. While onboarding can overwhelm and progression sprawls, it's fantastic for co-op players wanting near-endless content.

Warframe earns mention for enormous free content, a healthy community, and graphics settings that scale down to older machines when configured well. This slick co-op looter-shooter offers bite-sized missions and endless frames to pursue, with mobility and style defining the grind. While it requires setting tuning for very modest PCs and has a confusing early game, it rewards long-term goals and movement mastery.

Warframe tops this list because it delivers the deepest co-op looter-shooter experience available for free on Steam. Squads of space ninjas work together through missions with smart matchmaking, flexible 1-4 player scaling, and a decade of content updates. The build crafting, movement mastery, and role variety keep teams engaged long-term, while steady playerbase activity ensures quick queues and lively events.
