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 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

its good
fun
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

Its fun, its got a great world building premise. the different mechanics coalesce into a really well made game
Cataclismo m’a complètement captivé ! Le mélange entre construction brique par brique et tower defense est juste brillant. On prend un vrai plaisir à bâtir ses forteresses et à les voir résister face aux vagues d’ennemis. Chaque mur, chaque tourelle compte, et ça rend les défenses très personnelles. L’ambiance est super réussie : à la fois sombre et mystérieuse, avec une direction artistique magnifique et une bande-son immersive. La campagne est prenante, et les autres modes (Survie, Escarmouche, Créatif) offrent beaucoup de rejouabilité. Un énorme bravo aux développeurs pour leur créativité. C’est un jeu qui sort du lot et qui mérite vraiment d’être découvert. Si vous aimez les jeux tactiques et la construction, foncez !
E' un bel gioco. Lo ricorderò? Probabilmente no. Ha dinamiche viste e straviste di tower defense. La campagna è bella mentre la storia è ridicola e purtroppo lo scopri solo all'ultima scena (il momento "clue" sarà deludente). Mi è sembrato a tratti "raffazzonato" da un team inesperto, ciò perché ci sono dei bug irrisolti e delle scelte di design palesemente incomplete, che mi fanno pensare a una corsa per farlo arrivare "il meglio possibile" senza curarne molti aspetti. Lo consiglierei perché è generalmente divertente e ben fatto. Però si....nulla di che.
Super satisfying expand-and-defend gameplay with a really strong atmosphere. I like the building physics/rules but wish they had more options for complexity. It can feel like you just need to find the optimal design and then reuse it everywhere at times, but in the campaign you discover new things enough and the terrain varies enough that it only gets stale in the endless modes.
This game creates a mix of RTS and tower defence game. It provides enough mechanics throughout the campaign to keep your mind puzzling over how to best overcome the challenges presented. With resources gathering, attacks at night but also at day, causes enough for you to constantly be prepared. The building in this game is great, offers enough for anyone to just build whatever they need, yet for those who do not want to do that, they can open the steam workshop and select from community made structures. Campaign, with all side missions, takes around 12.5 hours while still having more to explore in terms of other game modes.
Good, fun game :)
