The zombie survival genre continues to dominate the market, from movies to video games and everything in between. With us humans having a profound interest in the undead, it is no wonder that developers are capitalizing on the appeal and, on top of one multiplayer zombie survival game currently taking Steam by storm, there are others to get your teeth sunk into.

Not only that, but these four zombie survival games are currently free to download on Steam. No catch. So, without further ado, let us find you your next best horror title.

4 Unturned

Unturned

In this open-world zombie survival sandbox extravaganza, players must fight to stay amongst the living as they scavenge for supplies, hunt for food, and build shelter in a world overrun by zombies. In Unturned, you will travel by land, sea and air whilst discovering hidden secrets and peculiar NPCs all whilst retrieving airdrops, scouting deadzones, and battling hordes of the undead. If you are feeling lucky, you can take on enemy players in PvP combat or just team up with them to share supplies and gun down some bandits. At a 'Very Positive' rating on Steam, this freebie is not one to miss out on.

3 Zumbi Blocks 2 Open Alpha

Launched back in 2023, Zumbi Blocks 2 Open Alpha is the official sequel to the 2013 free browser zombie game. Now stuck on an island, cut off from the rest of humanity, you will need to break free by finding the secret to escape hidden deep underground. However, you soon discover that the soil hides more than the tools of your escape, as the undead soon start to emerge.

Fight in first or third-person mode, loot a procedurally generated city for supplies and overcome powerful bosses as you fight to escape in this multiplayer survival title.

2 Walking Zombie 2

Described as "a zombie single-player shooter in modern polygon graphics with rich RPG elements", Walking Zombie 2 is a free-to-play hit set during a zombie apocalypse, tasking players with fighting zombies, bandits and dangerous boss monsters alike all whilst undertaking important story and side quests.

It may have first been released back in 2011, but No More Room in Hell deserves all of the praise. Now with all-out war taking over society, the chances of you surviving are slim, especially with millions of the walking dead currently shambling through the streets.

Featuring 1-8 player co-op, dynamic maps, a survival mode, and 30+ weapons to master, No More Room In Hell is the ultimate zombie survival experience, and as with all other games in this list, it is completely free to download now.
