Discounts
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): 0.57/day in the week to Aug 20 → 6.43/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,420 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.

Дуже гарне поєднання RTS і Tower defence жанрів. Сюжет по своїй суті хоч і простий, але гарно поданий і чіпляє.
TL;DR: Close enough, welcome back Castle Story In 5 hours i've seen enough to recommend Cataclismo. Really, if you like basebuilding games and horde like gamemodes, this game is the GOAT for you. and if you are like me, an unfortunate Castle Story fan, just buy it already, 'cause this is the closest you'll get of new content for it, the gameplay is very similar in the building and the endless gamemode part, but even so it is unique enough so its not just a rip off or something, seriously, its REALLY good. The art style being this, not so low poly models with the character art being very, idk, cool? yeah that'll do The controls need a little getting used to, with the shift scroll thing and stuff, not joy breaker or anything, just me being picky. The soundtrack too is really good, its not intrusive and you dont even realise its there untill you hear a sting or a bit of it, while you build, great stuff. Difficulty is quite out there, in a way that it starts easy enough, just for you to get ♥♥♥♥♥♥ by a group of enemies coming from the opposite side from where you were building up walls, it sucks, its great! seriously, the game is great, if you like games like the aforementioned Castle Story, or games like Diplomacy is not an option, Age of Empires (sort of, not quite but you get the point), and the likes you probably gobble this one up, great game

Pretty cozy settlement builder/tower defense game.
Fun and creative little game.
A mash up of several styles of game that alone would be less interesting. unique and interesting art direction.
Scratches the They Are Billions itch.
Fun single player RTS with some unique mechanics, a decent story, and now even a DLC! Definitely check it out if a smaller scale defense-oriented RTS is up your alley. Bonus points for crushing enemies with falling buildings.
Muy bueno el juego, esos si dificil cada nivel por las hordas de enemigos que te obligan a cambiar de estrategia, además de las construcciones
Very good
Seems like a pretty solid game, sorta give me the vibe of playing beseige in reverse, but beseige has a contraption building aspect I like more. This is also one of those games I cant help but try to optimize, but if I'm gonna spend a long time optimizing something, I'd rather do factorio. And for a campaign like this I'd rather go back to wargroove for the story. In short, it didn't really connect with me, but its a good concept done well, and I don't remember when I bought this, but I dont regret it
