Fight through the fog in this sci-fi roguelike deckbuilder where clever positioning, explosive chain-reactions, and the environment itself can make the difference between life and death.

Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 2.71/day in the week to Aug 30 → 3.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
As a deadly fog descends upon the world, the future of humanity rests in your hands! Assemble your train to determine your starting deck, plot your path through the bandit-infested world, and prepare for high-octane turn-based tactical battles where powerful synergies, clever positioning, and carefully planned chain-reactions determine the victor.

Choose from a variety of locomotives, carriages, and drivers to lead your expedition, with each decision adding a different set of cards to your starting deck, impacting the options and abilities you’ll have access to throughout your run. Gather resources to upgrade or purchase additional carriages that add more tactical tools to your deck as you journey through the fog and face off against a growing variety of enemy types with unique weapons, traits, strengths, and weaknesses. Will you rely on the spread and firepower of a minigun to quickly dispatch your enemies, use artillery to violently force chasing vehicles off-course, or hunker down behind shields and ram through your foes instead?
From hackers that can deploy decoys and take control of enemy vehicles to cranes that can push them around the battlefield, there are many ways to overcome the danger posed by the bandits and their leaders. Secure unique card upgrades and experiment with unexpected combinations to reveal powerful synergies – each with their own risks and opportunities.

With only a limited number of action points to use per turn, meticulous planning and careful execution will level the playing field as you face an enemy that constantly outnumbers and surrounds you. Force the enemy into the path of oncoming environmental dangers, push them off cliffs and into each other, or trick them into attacking one another as they telegraph their moves so you can plan yours. A clever use of Coal combined with a well placed Artillery Shot can force an enemy onto the tracks in front of you, only to be immediately crushed under your wheels. That same Artillery Shot could be used to destroy a leading vehicle and send it tumbling backwards to damage (and possibly destroy) everyone driving behind it, potentially paired with hacking cards that give you a chance to line more vehicles up first. The right order of operations will allow you to devastate the enemy convoys.
With over 170 cards featuring various status effects, support capabilities, damage outputs, and more, you’ll want to build a train that matches your preferred playstyle and unlocks powerful opportunities. Collateral damage, chain reactions, and manipulating the battlefield are all critical elements en route to victory.

Travel from region to region as you race to the edge of the fog, picking and choosing your path depending on a region’s specific modifiers and special rewards on offer. Branching paths within a region further allow you to finetune your route to the final destination based on the risks and rewards presented by each node along the way, ranging from battlefields to friendly waystations where you can upgrade and repair your train.
Every battlefield is different – some will see an ally come to your aid, others will give you less room to navigate and dodge the enemy, while still others might take place along the edge of a cliff creating a constant environmental hazard to use against your enemies. Many battlefields will offer a combination of factors that can help or hinder your advance, rewarding you with additional cards, modifiers, and scrap resources to use on your journey ahead. Chop shops and depots allow you to repair your carriages and locomotive, potentially giving you the opportunity to upgrade them and unlock additional cards, or buy and sell carriages to further modify your deck. Meanwhile, random encounters can provide rare opportunities in an otherwise unforgiving landscape, and boss battles at the end of each region will pit you against special characters on the battlefield, each with their own unique backstories and abilities to go with them.
Metaprogression allows you to unlock additional carriages, drivers, and locomotives to seek out new combinations and opportunities for future runs, or focus on upgrading your favorites to unlock even more cards to use in combat – the bandits are relentless and unforgiving, and while your choices during a run will have a significant impact, your choices between runs can unlock entirely new options to explore.
Fogpiercer puts you at the head of a rampaging train as it races towards safety and the future of humanity – intense turn-based tactical battles will see you constantly outgunned and outnumbered, but a shrewd tactician will always find a way to keep things on track.
Sums Steam only; Xbox, GOG publish no volume signal, so the true total is higher by an unknown amount.

One of my favorite games I've played this year. Anything that reminds me of Into the Breach can't possibly be bad. The combat puzzle gameplay, which relies as much on repositioning enemies for indirect damage as it does on direct attacks, is super snappy and addictive. I was initially turned off by the deck-building aspects, but that layer actually adds quite a bit to the game. There can be a bit of a difficulty spike on some of the bosses (especially if you're not very smart like me), and the controller support - while generally great - is a little flaky when selecting your train cars in the shop and station screens, but the devs have been very responsive to feedback and making steady improvements to those minor speed bumps.
My all-time favorite game is Into the Breach and I'm a huge train dork, so I'm a little disappointed that no state has passed legislation allowing someone to marry a videogame.

I'm a big fan of roguelike deck building games and this one is special. Unlike many of them which have a very static battle, this game has a very dynamic battlefield with the other vehicles moving around and taking different positions. It makes you consider your own train location and how to use different train cars to solve the new state of the battlefield each turn. Using different cars feels great as they all work uniquely, it's fun to blow up cars with the mini gun but also find it so fun to use the crane to move the enemy around so they attack each other. Check this game out!
Very cool deck building battler. Has the feel of a western movie fight with cars alongside a train. Satisfying mechanics, seemingly inspired by Slay the Spire and Into the Breach but feeling entirely original in their own right. Would definitely recommend a try if you have any interest in deck builders
iz fun
Fogpiercer's card mechanics are basically identical to Slay the Spires, in this way that I knew shield didn't persist between rounds because. The thing it adds is that you are a train on a grid and your enemies are vehicles on that grid, and you can move them with artillery. It does a very good job of making the combat satisfying. One of the first things you learn is that if two enemies are going to shoot at you, you can move your train out of the way and they will blast each other. This is always funny. Shooting artillery at an empty space will push enemies away, and when enemy vehicles die the wreckage will skid back into other vehicles. In short, you can turn the general area into a NASCAR arena. The downside for me is that 100% of my deaths so far have been from failing to notice that step 2 of my bombardment sent something crashing into my engine and exploded it. But I don't really care because watching it go off is funny.
Mechanic quick rundown - Card Builder + Into The Breach + FTL, very fun game. Like Megabonk you will always unlock something new every run even if you don't make it. 25 hours in and I didn't even realize it. New unlocks comes with entirely new mechanics which makes the game fresh to play, even the plot and NPC changes as the game progresses. It knows how to keep things fresh basically. I have done a few playthroughs recorded as well.
fun game easy to learn and has a nice learning curve, fun to just keep trying to get further.
What a good game! Congratz guys
机制还行,但是不够深,不够好玩。而且譬如钩锁车的设计也非常别扭。当甜品打发周末晚上的时间还行吧。总体来说让人玩的想睡觉。
