Survival TTRPGs: You Think Survival Is Scarcity. It Isn’t.
This is part of my ongoing series on system structure and pressure models—see my previous: Heroic Fantasy TTRPGs: The Real Test (And So Many Games Fail It)
This post looks at what survival games do on a system level. If you’re designing a survival TTRPG, tracking resources like torches and rations isn’t enough. What really matters is the kind of pressure your mechanics create and enforce. If your rules let players replace resources as quickly as they use them, or if setbacks just make characters stronger, your mechanics are working against your premise.
Like my earlier posts, this analysis is meant to offers a blueprint. If you want to build a survival game these are the key parts you need. If you leave one out you will know exactly where the system might fail, or where you’ve chosen to change things for a different experience.
Tone and setting are only half the game. Art, lore, and atmosphere matter, but they rely on a solid system of rules underneath. If your rules don’t support the theme of your game, the GM has to do all the work. If the game doesn’t drain resources faster than players can get them back, the survival feeling depends primarily on the GM limiting supplies. As soon as players find a steady way to restock or rest safely, the pressure disappears. A real survival system keeps the challenge going, even when the GM isn’t paying close attention.
Survival is about more than just scarcity; it’s about the trajectory of play. The core constraint is dC/dt ≤ 0, where C is the group’s capability: health, gear, ammo, money, mobility. It should not go up over time, at best it stays the same. You can’t really get ahead. If players can always build up extra resources through smart play, the game stops being survival and becomes something else.
Methodology
These five criteria come from looking at what games actually enforce through their rules, not just their feel at the table. I researched games labeled “survival” over the past fifty years, going as far back as The Morrow Project (1980) and Outdoor Survival (1972)! I identified the common threads across the industry that let some systems sustain a survival structure, while others didn’t. This is the pattern those games share in practice: a tool designers can use to predict, at the design stage, whether their survival game will hold.
The Five Structural Criteria
These criteria are about whether your system structurally enforces dC/dt ≤ 0 across a campaign. If you miss one, you’re leaving GMs to handle what your mechanics should cover. Use these checks to see how your survival system will hold up over time. If your game doesn’t meet all of them, you can reliably predict that survival will be intermittent at best and eventually give way to some other kind of play.
1. Playing the Game Costs Resources. Does playing the game use up more than it gives back? Play should use consumables or abilities faster than the system replaces them. Survival systems turn play into a net loss. If players always end up with extra, it’s not really a survival system.
2. Recovery Isn’t Free. Is healing just a reset or does it cost something? Getting back to normal should use up resources, take time, involve risky rolls, or cause other losses. In heroic systems, recovery is like hitting pause: rest for free and wake up more or less fine. In survival systems, recovery is a transaction you might not always be able to pay for.
3. Setbacks Make Things Worse. Does failing make it harder to succeed next time? Setbacks should raise the cost or risk of future actions, not just cause temporary inconvenience. In heroic systems a fighter at 1 HP still fights at full strength, but in survival systems, injuries make it harder to stay alive.
4. Time Itself Is Hostile. Do resources deplete even when nothing is happening? The key is whether avoiding risk can stop things from getting worse. If careful play can completely stop resource loss then it’s not a survival system—it’s just a game where smart players can avoid running out.
5. You Can Never Outgrow the Scarcity. Can players ever get so rich or well-equipped that they’re safe? Skilled players might break even, but the rules should never let anyone get permanently ahead. In survival systems, just breaking even is winning.
So you know, C1 looks at what happens each session, while C5 looks at the whole campaign. Playing the game always costs resources, and you can never fully escape that.
The quickest way to spot a fake survival game is to see what happens when the party rests. In a real survival game, rest costs something. If you can heal for free just by waiting then you’re really playing heroic fantasy, just at a slower pace.
The Material Downward Pressure Loop
Survival systems do more than create scarcity, they build the dC/dt ≤ 0 condition right into the game. Players’ capabilities don’t grow as the campaign goes on. The focus isn’t on difficulty, but the trajectory.
You need to build a core loop: Engagement, Expenditure, Degradation, Maintenance, then back to Engagement. When players take action, the mechanics should make sure it costs resources like time, items, wear, or money. Good systems turn these costs into damage, scarcity, debt, or exhaustion. The rules should make players pay just to keep things stable, not to advance, and then repeat the cycle. Your math should ensure every action reduces capability, and even success might not lead to a net gain. If your rules enforce this loop you can predict whether your survival campaign will stay true to its theme or shift into something else. If players can skip any step through careful play or a generous GM, the survival structure becomes weak.
This loop is crucial because it defines the game’s focus. You can create it on purpose or break it by accident, depending on your mechanics. Heroic systems are like a ladder: you climb, grow stronger, and change the world. Survival systems are more like a treadmill: you can keep your balance or slow things down, but the system resists any lasting progress.
That’s what separates survival from other pressure models:
Heroic systems: Setbacks wound you. Recovery restores you. Growth makes you stronger.
Grimdark systems: Fighting evil corrupts you.
Horror systems: Exposure erodes the self.
Survival systems: Just existing costs you.
Why People Play Survival Games
Survival games aren’t just about making things scarce. Instead, they’re designed so that every action costs more than players can really afford. Recovering uses up resources, nothing comes back easily, and the game pushes back no matter how well you play. When this kind of pressure is part of the main gameplay loop managing resources isn’t just a side task, it becomes the main strategy.
That’s what makes survival games appealing, but it’s a unique kind of appeal. Players who pick survival aren’t focused on winning, they want the satisfaction of just holding on. Survival games don’t ask how far you can go or how you change under pressure: they ask if you can keep going at all. For some, keeping things from falling apart feels better than any big victory. In these games, winning simply means you’re still in the game.
Players who need upward trajectory will eventually lose interest, since the game’s rules don’t allow for that no matter how well they play. That’s not a problem, that what survival games are. This is also why many survival games add a way to shift into building or settlement play; not because survival doesn’t work, but because most groups eventually want to move from just surviving to creating something new.
Survival Game Systems
These systems show how different mechanical approaches can all produce the same dC/dt ≤ 0 trajectory. They are the games this model was extracted from, and they are also the games it correctly predicts as true survival when you apply the five tests.
Torchbearer (2013, 2021, Olavsrud/Crane)
Torchbearer 2e is really the gold standard of survival games. The focus is on making it through dungeon expeditions while racing against time. Every four Turns, your party picks up Conditions like Hungry, Thirsty, Exhausted, Sick, or Injured, which make things harder. Every action uses up time and resources, and even careful play can’t stop the steady drain because time always moves forward. To recover you have to camp, which takes Turns and requires Checks that might fail. The real challenge is keeping your group alive long enough to recover and try again.
For players who like tense resource management and always feeling the pressure, Torchbearer makes dungeon crawling feel like a survival puzzle. You have to balance risk, time, and limited supplies, so even small victories feel rewarding. You can try the free Dread Crypt of Skogenby! introductory adventure. There’s also a nice YouTube video of a conflict demo.
Red Markets (2017, Caleb Stokes)
Red Markets is a singular game, as it fully meets the criteria for both a pure grimdark game and a pure survival game! Most hybrid games transition between pressure models, starting with survival and then shifting to other styles, but Red Markets is a true fusion. The same system drives both the moral and material challenges, since debt acts as both a corruption track and a drain on your resources. Showing compassion increases your debt, and too much debt can end your character. Being good makes you poor, and being poor kills you.
Each mission in Red Markets can leave you worse off, even if you succeed. You have to pay for things like rent, food, and dependents, and you use up gear like ammo and batteries during jobs. Healing, repairs, and therapy all cost Bounty, so you’re always choosing between making it through today and being able to afford tomorrow. Winning isn’t about getting rich or powerful, it’s about keeping your crew together long enough to take on another job. If you like games where money, gear, and mental stability are just as important as weapons, Red Markets is a great choice.
Begin with the free Quickstart Guide, and run a short first job. There is also a great, self-contained Session Zero that a fellow blogger wrote that I recommend. You may also consider an extremely useful actual play podcast called The Brutalists which demonstrates the system.
Miseries & Misfortunes 2nd Edition (2019, Luke Crane)
Miseries & Misfortunes is about surviving life in 1648 Paris when your own lifespan is a resource. Created by Luke Crane, known for Burning Wheel, this game stands out from others. When you use Exertion to reroll failures or avoid danger, you lose years from your Mortal Coil. Getting better takes time and is expensive, whether you rest, get treatment, or rely on social help. As you rise in status your upkeep costs go up, so even success wears you down. The main challenge is clear: can you build a life worth living, knowing every decision shortens your time?
If you want a survival game that feels personal and meaningful, this is a great choice. You can make progress, but every step forward costs you something real. Here you’re fighting to survive yourself, not just the city. The core books are enough to begin, but for more detail, check out Paris 1648.
Twilight: 2000 4th Edition (2021, Härenstam/Lites/Keeling et al)
Twilight: 2000 is set after World War III, where you have to survive as military systems fall apart. Each day is split into Shifts, and actions like marching, scavenging, or fixing things use up fuel, food, and water. Even when you succeed your gear can break down, so you need to repair it with limited supplies. Recovery is slow, and serious injuries can leave lasting problems. The main challenge is keeping your group going over time; you can find some stability, but you can never get rid of the constant wear and tear. Safety is always uncertain, and stability is something you have to fight to keep.
If you like strategy and making tough choices, you’ll find every decision matters here. Twilight: 2000 makes logistics, exploration, and combat into a tense survival calculus where just keeping your group going is the main challenge. The book includes the starting scenario, Escape from Kalisz. If you want to listen to an actual play podcast, here you go.
Coriolis: The Great Dark (2025, Kostulas/Karlén/Grip/Härenstam)
Coriolis: The Great Dark is about keeping your ship running as interstellar systems collapse. Your crew explores alien ruins, but every trip means paying Slipstream Fees, Docking Fees, and covering supply costs. Supplies run out as you travel, and you can’t fully restock without taking risks. Recovery is only partial, and failures can leave lasting physical or spiritual scars. Here, survival isn’t about finding treasure, it’s about keeping your crew able to return for the next mission. You can’t escape scarcity, only plan for one more journey into the dark.
If you enjoy tense exploration, where every mission could mean permanent loss, Coriolis is for you. The game makes travel, managing supplies, and facing hazards into a constant, high-stakes challenge. You can start with the adventure included in the book. I found an actual play video for this one as well.
What Gets Mislabeled as Survival (And Why That Matters)
Understanding why some games fail the five-part test is just as helpful as knowing which ones pass, because shows what players really want compared to what survival games offer. Once you understand the pattern, you can look at any “survival” game and predict if the rules will hold up or slide into something else instead.
Shadowdark is a deadly exploration game, but it isn’t really a survival system. The real-time torch rule means time always matters—if players spend 20 minutes talking they lose 20 minutes of light, and the dungeon gets much more dangerous in the dark. Still, the game doesn’t enforce C2 (frictional recovery), C5 (no late-game escape from scarcity), or the ongoing economic pressure that defines true survival games. It’s a lethal OSR game, but not about scarcity.
Forbidden Lands starts out as a survival game that later turns into a domain campaign, failing C5. It begins with real attrition, but collapses once you build a Stronghold. It does more than stabilize survival it solves it, so it’s not a survival game anymore. This is actually a sophisticated feature of the game: a transition from hex-crawling survival into a macro-level stronghold management game, using the same engine. You start as a scavenger and can end as a lord.
Mutant: Year Zero starts as a survival game but moves away from that over time. Early on, there’s great attrition: Resource Dice wear down, the Zone is dangerous, and mutations have lasting effects. However, Ark Projects turn scarcity into lasting infrastructure, which solves the food problem and makes gear upkeep easy. The game is designed for players to rebuild civilization, not just survive, so it becomes more of a post-apocalyptic settlement simulator. That’s intentional, but it clearly fails C5. MYZ is meant to begin with survival, not stay there.
Salvage Union is a good example of a game that feels tough without actually being a survival game. The Crawler’s upkeep means you always need to go on scrap runs, so the campaign keeps pushing for new expeditions—C1 is met. But after each run, downtime on the Crawler restores main mech resources and allows repairs, which removes much of the attrition between trips. Some character options can even stop the Crawler from wearing down, so long-term pressure becomes a problem you can solve. C2 fails (recovery resets too much), and C5 fails too.
Alien RPG (in campaign mode) is close to a survival system but fails C3 (Setbacks Make Things Worse). Stress is the main pressure mechanic, but it works both ways: adding Stress dice to skill rolls can actually make success more likely right away. The catch is that any Stress die showing a 1 triggers a panic roll. When you push failed rolls, you gain Stress and get better chances to reroll at the same time, so failing usually means “better odds, but worse risks.” Failure doesn’t limit your options as much as it just makes you gamble. This works well, though, since the game aims to be horror, not survival.
Zombicide: Chronicles fails C1 (Playing the Game Costs Resources). The campaign has a Shelter Phase, but it’s just an abstract break for restocking and planning, not a real upkeep system. The main mechanic is Adrenaline: as you succeed, you earn Adrenaline that unlocks better skills as the mission goes on. When you return to the Shelter, Adrenaline resets, but long-term Experience upgrades stay with you across missions. So, playing the game always turns action into more power. That’s more like a heroic slasher with a safehouse, not a survival game.
Conclusion
To create a true survival system you need to move away from the usual power fantasy and focus on making maintenance itself feel rewarding. Many so-called survival games are really just heroic adventures with extra tasks. If you want to design a true survival RPG, use these five criteria as the blueprint.
Designers should ask themselves, “How does ongoing play affect a player’s abilities over time?” Using this model helps you not only understand current games but also predict if your survival system will work or shift into a different genre. If your main gameplay loop enforces dC/dt ≤ 0, and surviving always costs more than it gives back, you have a true survival system. If players can eventually escape the challenge for good, the game isn’t about survival. Make sure you know which type of game you want before you publish.
Please, if you know a game that meets all five criteria that I missed, I want to hear about it! Tell me about it in the comments below.
