For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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
Lead the last survivors in the aftermath of the Cataclismo as a corrupted world seeks to destroy all that remains of humanity. Build fortresses brick by brick, designing intricate, towering structures of wood and stone to fend off waves of Horrors as they attempt to overwhelm your band of survivors. Command powerful units in their stalwart defense, coordinating their varied capabilities as you race from breach to breach. Lead forays into the unknown to secure the vital resources needed to grow your military might and construction capabilities as you hold fast against the ever-growing onslaught – siege after siege, night after night.

Far from the relative safety of the Last City, your citadels and outposts hold back the hordes of Horrors before they can strike at the heart of humanity. Build impregnable fortresses across multiple biomes using an intricate building system that allows you to design your defenses with full freedom and strategic creativity, adapting your plans to the surrounding environment. Take advantage of natural chokepoints, height advantages, and local resources as you strategize for the challenge of each upcoming night’s attack.
A highly modular building system allows you to design your fortresses exactly as you desire – one piece at a time, with blueprints you have designed in advance, or using community creations shared by other players. Use your hard-earned resources to build structures that grant access to previously unreachable parts of the map, or construct fortifications that deny the Horrors access and provide your troops safe vantage points.
Build cheaply and quickly using wood, or establish quarries and use durable stone to better withstand the onslaught. Keep an eye on structural integrity and load-bearing columns as falling pieces will kill friend and foe alike, often creating unique opportunities to crush numerous enemies with cleverly placed vulnerabilities.
Adapt your fortress to growing needs as you acquire new tools and expand in an attempt to secure all the resources needed to sustain a powerful defensive force. Optimize the path from resource deposits to your warehouses with well placed structures and use rooftop construction to make the most of your limited space.

Though the Horrors may test your defenses during the day, only at night do they pour forth in full force. Spend your days exploring the world and pursuing the growth of your fortress, but as the sun starts to set, you would be wise to position your forces in preparation for the night’s onslaught.
Skillfully command soldiers ranging from sharp-eyed bowmen to explosive cannoneers to respond to an ever-evolving situation as new Horrors emerge. Draw the enemy into chokepoints lined with devastating traps and ambush them raining down fire arrows and pots of poison flung from your battlements. Maneuver your troops into precise tactical positions to take advantage of special traits and abilities made available as they upgrade, positioning them at heights that let them perform at their best – a wise architect can design fortresses that allow for a tiered defense.
Build vital structures to sustain your defenses against the growing threat and unlock higher levels of prosperity alongside new technologies. Resource gathering outposts, unit recruitment centers, and housing for your citizens all directly and indirectly support your troops in their efforts. Should the walls falter, even your citizens' homes can be used as a secondary layer of defense – you must protect the citadel at all costs.

Cataclismo contains all three of: an epic single-player narrative campaign; a skirmish mode featuring hand-crafted maps; and an endlessly replayable challenge mode that puts you to the test on procedurally generated maps where you fend off increasingly dangerous waves of Horrors. A complex map editor gives you the ability to design and share skirmish maps of your own to challenge the community while the intricate construction system will allow the architecturally inclined to build and share blueprints and help others in their defense against the Horrors.
The Cataclismo left the world devastated. But all hope is not lost – lead humanity through the darkness to a bright future as you design grand fortresses and command troops in real-time battles against a seemingly endless horde that will stop at nothing to see your people destroyed.

[h1][b]The World in Mist[/b][/h1] [quote]The world has been plunged into a mist, and humanity is on the brink of extinction. You play as Lady Iris, mankind's last hope. You must leave the last city, Hogar, and embark on an expedition to find the mysterious pearl that can save humanity. The adventure won't be easy, but the stakes are high.[/quote] [h2]Daylight[/h2] At first, you can not just stand at your Citadel – you need to explore the surrounding area and start gathering resources as fast as possible. You will collect wood from sawmills, stone and minerals from quarries, and oxygen by building air filters up high so they can work efficiently. Wood is essential early on for building basic structures and creating more workers. Stone is crucial for stronger defenses. Minerals are needed for advanced buildings and upgrades. Oxygen is required for buildings, units, and workers. Balancing these resources and placing your gathering buildings intelligently makes all the difference between barely surviving the night and holding your ground against swarms of horrors. At the beginning, it can feel hard, but once you learn all the mechanics and understand them correctly, you will be able to complete all levels even on extreme difficulty. [h2]The Night is Nearly Here[/h2] A campaign is not only about base building, but also includes expeditions where you have limited units, or you control only Lady Iris. It is a nice addition and perfect for storytelling, which I think is decent. The entire atmosphere of the game is well-crafted, thanks to its original visual style, engaging soundtrack, and interesting lore. After a story mission, you can try to prove your skills in skirmishes where you must survive four nights, or you can try to survive as long as possible in survival mode. Also, there is a sandbox where you can do whatever you want, or you can create your own level and publish it in a workshop that is useful for blueprints – premade structures too. [h2]The Horrors are Coming[/h2] I did not encounter any bugs during my playthrough. It is rare nowadays, but the optimization could be slightly better in survival mode. One thing that would need some correction is the prosperity levels that are used to unlock better buildings and units. There is no reason to upgrade beyond level two or three, as it requires a lot of resources that could be spent on upgrades for the three basic units: Bowmen, Lobbers, and Captors, or to produce more units and reach the army limit. Yes, higher prosperity means you can have more units. But playing on extreme difficulty, there was no time to collect enough resources. So my tactic was to stick with the basic units and combine them with boost buildings, such as fire arrows and damage boost flags. This works well on lower difficulties as well. Thanks to this, I was not able to use other units (if I do not count given units by script during missions): Cannoners, Ballistas, Hunters, and Partisans in city-building missions, even in my first playthrough on medium difficulty. [h2]Is it over? Yes, it is![/h2] I enjoyed the rest of the gameplay, especially building various walls and platforms to make them stable and strong. The wall physics are good, and you have to think about what will happen if one block is destroyed: will the rest of the wall stay up, or will it fall down too? For thinking, you can pause the game any time and if your plan fails, rewind time anchor (load save) is your saviour. [b]I highly recommend Cataclismo to anyone who enjoys RTS or tower defence games. Even if you don't usually like these genres, the game is still worth trying. It offers a unique combination of base building, a LEGO-like construction system, tower defence, and RTS mechanics packed into an original visual style.[/b] [table][tr][td][h2][b]Cataclismo 8.5/10[/b][/h2][/td][/tr][/table] [table][tr] [th]🟢 Wall building and physics 🟢 Campaign 🟢 Original idea 🟢 Atmosphere [/th][th]🔴 Prosperity is expensive [/th][/tr][/table]

The style and the UI are pretty good, yet the game still lacks depth in its systems and level design. It sucks that there is so little to learn and gain in each level that I wish the levels didn't end at all. Also the game allows you to use the steam's workshop so early that it almost ended the way i wanted to solve things myself. It became kind of boring because problems I encountered could be solved too easily with the help of the workshop, which was kind of a bummer.
balance could be a bit better, it feels like most optimal strategy is to rush tier 3 on every map to get best results, campaign missions that force you into using pieces instead of actual economy are awful, you give me so much wonderful terrain to build on and you limit me with pieces. mission 8 was so anticlimatic for me that i just resolved it by building around the outpost and recycling pieces when they were too damaged, at least game gives you the option to cheese it cus i would probably drop the campaign at that point overall it's a good game with neat climate, and max difficulty actually forces you to experiment before figuring out the best approach, im kinda on the fence with how short most maps are, but i might just get my fill after getting to endless maps blueprint system is one of the best features i seen in building games, and i wish it was implemented more
Enjoyed the campaign! City builder levels are especially fun - although I did find it hard sometimes to toggle difficulty between "I won this level easily" and "I'm so rushed I definitely won't win" ~ I couldn't always find the "this is hard but doable" sweet spot. But overall, I was glad I bought and played the game - nice work devs.
Challenging, resource-managing, defense game. The story and designs are nothing groundbreaking, but they are efficient for what thy are. It was thoroughly addicting having to prep for the next attack and learning your strategy failed spectacularly, just to restart the day and try again. Even with the same resources, modifying your tower strength and troop layout can make or break your night. Highly recommend!
got a item that caused me to pay 100 scrap to upkeep i Dont have that much scrap so i ended up never being able to buy the warehouse. i was negative 14 production with no way of increasing it.. because i need scrap to upkeep which as soon as i produce any it gets taken away. Cards should be removable or sold for resources. made my 3 hour game completely broken. as well as some of the troops don't make it to my settlement so i don't get the bonus. I'm on night 15 with 7 upgrades.
Game idea is great, would love to keep building my castle in so much detail. The problem is the enemy spam is ridiculous. You barely have enough resources to make 5 archers, the enemy attacks from 3 directions with dozens of units, no freaking way you can defend. Gave up on it quite fast.
I was super hyped for this game after watching the trailers. I will say it is a 6.5/10 or a 7/10 at best. It is really no more than a mediocre tower defense where in between "waves" you build up a very simple basic town to farm resources to then better your defenses. That may sound fun but i didnt have a good time with it. Bland color pallet and story and repetitive gameplay loop
Really great game. I'll keep it short, I love just about everything about it. I have had two crashes in my 5 hours though that completely blacked out my computer screens. Aside from this, literally no reason to not recommend thus far.
A promising additional layer for a horde defence that fails on execution. Although the initially charming theme, art style and polish, are effective at drawing attention away from the underlying mechanics, after enough hours of play they unfortunately become clear. Cataclismo brings the unique angle of using Lego style building to the hoard defence genre, a task that swiftly becomes tedious and time consuming, when the unique selling point becomes bore the rest is simple not enough. There are plenty of QoL issues, and I’d imagine they will be patched over the life of the game. The core issue being once you figure out how to optimise the construction systems, there’s nothing else.
