Key Takeaway
Five free survival games on Steam — Once Human, Fallout Shelter, Unturned, Muck and No More Room In Hell — each offer a different take on the genre for players who love survival games.

You don’t need to spend money on pricey blockbusters to enjoy survival games. Steam has plenty of quality free options, from base building to fighting off zombies.

The appeal of survival games lies in starting out with almost nothing. From scavenging for resources and crafting items to building shelter and dealing with sudden dangers, every game finds its own way to test how well players can adapt.

Once Human - Surviving a Post-Apocalyptic World

Once Human drops players into a post-apocalyptic world overrun by strange creatures. Survival revolves around exploring the map, gathering resources, fighting and building a base.

One of the game’s highlights is its building system and fairly varied weapon customization, which give players more options while exploring and handling threats. Although it no longer makes the splash it did at launch, Once Human is still worth a try for anyone looking for a free survival game with a large world to explore.

Fallout Shelter - Managing a Vault After Disaster

If you’d rather experience survival through management, Fallout Shelter offers something different. Instead of wandering the wasteland yourself, you take charge of a vault after a nuclear catastrophe.

Food, resources and dwellers all need to be allocated carefully to keep the community running. Attacks from outside or incidents inside the vault can happen at any moment, forcing players to keep expanding and defending their shelter.

Unturned - Surviving a Zombie-Infested World

With its simple art style, Unturned may not impress visually, but it offers a surprisingly rich set of survival systems. It’s also a good fit for anyone who loves zombie games.

Starting with very little gear, players have to find food, water and essential items to stay alive. Besides zombies, factors like oxygen and radiation can also become dangers while exploring.

Muck - Survival Meets Roguelike

Muck delivers a faster-paced experience by combining the survival formula with roguelike elements. Instead of spending months building up a single world, every run puts players in front of fresh challenges.

Gathering resources, crafting, building and upgrading your character are still familiar activities. However, enemies grow steadily stronger, making gear preparation and how you choose to deal with threats all the more important.

No More Room In Hell - Hardcore Survival Against Zombie Hordes

Rounding out the list is No More Room In Hell, a game for those who want a harsher zombie experience. It originally started as a Source Engine mod and is steeped in the atmosphere of classic zombie films.

Resources are limited, your defenses won’t always keep you safe, and hordes of the undead can quickly put the whole team in danger. Coordinating with teammates and using items wisely are key to survival.

5 Free Games, 5 Different Ways to Survive

Once Human, Fallout Shelter, Unturned, Muck and No More Room In Hell are all free on Steam, but each approaches the survival genre in a completely different way. Once Human focuses on exploration and building, Fallout Shelter leans into management, while Unturned and No More Room In Hell lean heavily on zombies. Muck, meanwhile, suits players who enjoy quick, highly replayable sessions.

With that kind of variety, these games are well worth trying if you’re looking for a new survival game without having to pay for one.
