5 Free Zombie Games You Can Play On Steam Now

Zombie games are always in fashion, whether you’re mowing down endless hordes, scavenging for your next meal, or just trying to survive another night. The best part? If you’ve yet to try this spooky but thrilling genre, you don’t have to pay a single buck to dive into the chaos. Steam has a range of free-to-play zombie titles, from co-op slaughter to survival horror challenges, proving that some of the best undead experiences available right now won’t cost you a thing.

If you’re a PC gamer with Steam as your go-to storefront, you’re already in one of the best places to find free zombie games. Sure, there are plenty of excellent paid experiences too, but beginners—especially those who aren’t comfortable with the horror setting—may not want to spend money before deciding whether the genre is for them. Besides, some days you just want to play games that don’t take a toll on your pocket, yes? In that case, these are the best games to add to your library.

Dead Frontier 2

Let’s start with Dead Frontier 2, a highly rated survival-horror MMO that drops players into a city devastated by a zombie outbreak. Typical, right? Not really. Instead of constant action, the game leans heavily into exploration, scavenging, and survival. Every step outside of a safe zone feels dangerous as you scour abandoned buildings for weapons, ammunition, medical supplies, and crafting materials while avoiding all the deadly infected around every corner.

The game also features RPG-like progression where you level up your skills, upgrade your gear, and trade items via a player-driven economy. Join forces with other survivors or go solo, depending on how you like to play. There's also the opportunity to go head-to-head with other players in PvP, adding an additional threat to a world already crawling with them.

If you’re after a slower-paced, more atmospheric zombie game where planning is just as important as shooting, Dead Frontier 2 is definitely worth a try. While its multiplayer community has died down somewhat, it's still an active game, with a current summer event indicating the developers' continued support.

Unturned

Don’t let Unturned’s blocky looks fool you; it’s one of the most feature-packed free survival games on Steam. Players begin with almost nothing and must scavenge for food, water, clothing, weapons, and medical supplies while fending off zombies. The game also has several large official maps with different environments, challenges, and loot to discover.

Unturned isn’t just about surviving: You can build bases, drive vehicles, grow crops, fish, and even make your own content via the Steam Workshop. Online multiplayer servers offer co-op and PvP gameplay, ensuring no two sessions are alike. Unturned is one of the most popular free zombie games on Steam and has been updated for years, with an active community.

Recently, Unturned developer Smartly Dressed Games made the source code for the game publicly available, opening up the potential for more drastic community overhauls than ever. It's rare for a free-to-play game to consistently earn love from its fans, but Unturned has certainly managed to do so. Nearly 10 years after its full release (and several more since it first appeared in early access), this free zombie game has crafted a true legacy on Steam.

Codename CURE 2

Codename CURE 2 is a zombie first-person shooter that focuses on teamwork more than lone heroics, so it’s great if you have a group of friends to play with. Players cooperate to fight off zombie hordes and accomplish mission objectives on different maps. There are various character classes, each offering unique abilities and gear and encouraging squads to work together and coordinate their roles instead of just running and gunning.

As a sequel to Codename CURE, it takes the original and enhances it with better visuals, improved gameplay mechanics, and overall polish, but still adheres to the familiar co-op formula that fans enjoyed. The gunplay is satisfying, the infected enemies are varied, and the objective-based gameplay means that each match is engaging. While it doesn't reinvent the wheel compared to the original game, it also avoids losing any of its charms.

The biggest selling point of Codename CURE 2 is how classic it feels, tapping into the appeal of classic co-op shooters more than some big-name titles like Killing Floor 3 have managed to. It's still a little light on some features, but as it's only been out for a week, there's plenty of time for the game to expand into a more comprehensive experience. If you’re looking for a free alternative to games like Left 4 Dead, this is one of the best options on Steam.

The Walking Dead: No Man’s Land

Based on the hit TV series that needs no introduction, The Walking Dead: No Man’s Land is a tactical game about surviving the apocalypse—but it’s not your usual zombie experience. Instead of real-time action, players command a squad of survivors in turn-based battles, moving their characters carefully and planning attacks against walkers and hostile humans alike.

As you progress, you’ll be recruiting familiar faces from the series, upgrading your camp, unlocking better weapons, and taking part in seasonal events and daily challenges. Each mission is rewarding, and strategic decision-making is as important as putting together a great team. Unfortunately, its mobile roots are obvious, with plenty of microtransactions and an intense grind if you want to avoid them.

If you have some tolerance for that kind of game, though, there's a lot to love here. The Walking Dead: No Man's Land might not be as iconic as Telltale's The Walking Dead series of games, but it's still a far cry from the sheer disappointment of The Walking Dead: Survival Instinct or Destinies. Fans of strategy games and The Walking Dead franchise alike will find plenty to love here.

Propagation VR

If you’ve got a VR headset, Propagation VR is one of the most intense free horror experiences on Steam. Set in a dark subway station, the game has players fight off waves of zombies and scary mutant creatures that just keep coming. Realistic weapon handling and manual reloading make every encounter feel immersive, while the eerie atmosphere keeps the tension high throughout.

Like many VR games, it won’t take long for you to finish, but Propagation VR is a fantastic showcase for virtual reality horror, and its short runtime avoids any sense of bloat or a slowly diminishing fear factor. The graphics are detailed, the sound design is great, and the controls are responsive, all of which add up to plenty of terrifying moments. Even if horror games typically fail to make an impression on you, venturing through dark environments in VR can make all the difference in the world.

Of course, this isn't quite as accessible as some of the other free zombie games on Steam, as you’ll need the VR gear for this one (along with $10 if you want to upgrade to the co-op experience). Another paid option is Propagation: Paradise Hotel, which puts a greater focus on the storytelling. For those who both have a headset and are looking for a free Steam game that fully embraces zombie horror, though, Propogation VR is an easy recommendation.
