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 2,515 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.

Neat and lovely
Enjoyable tower defense but did not hold my long term interest.
Un très bon jeu, avec une bonne histoire, il peut être un peu brutal et compliqué donc évitez le mode Extrème au début, de plus la communauté partage des préconstructions et des missions très sympathiques. On a une grande liberté pour la construction, permettant de rendre les choses très belles.
Top Game!
Good
优化💩画面👍,卡第五关,教程BUG,跟本玩不了后面的😒,
Cataclismo is a Real Time with Pause Defense Strategy game. You will build economic buildings to harvest resources, explore with your units, and then plan elaborate walls and defenses to survive the hordes that come at night. What makes this game unique is the verticality that buildings and your defenses have. Your units deal bonus damage if they are at the right height, so to maximize efficiency you will build a wall with some windows at the low level, and some platform at the high levels, but also need to work around the terrain, maybe add some traps, and keep the walls thick to actually survive the night. You can integrate your economics buildings like air collectors and houses into your defenses since they can act as platforms or need to be higher up themselves. Cataclismo is so close to being a great game, but as the devs have said the game was always intended to be a campaign first and as a result, the "skirmish" and "survival" modes just do not quite work as well as you'd hope. It is still a good game, but sadly it left me wanting more even with unplayed content. The campaign itself is quite good, with a good story, great art, and a variety of levels. Again unfortunately though, half of the campaign levels are short exploration missions where you do not build a base and that offer little challenge feeling like filler, and even some side missions are "tower defense" missions where you defend a point with limited materials. Both these missions types feel watered down versions of the main game, leaving you just a few real, proper levels. Those levels are great, and are when the game is at its best, but that is maybe 10 hours of content? You have all these scenarios, game modes, and other types of ways to play the game, other than the one they actually built the system for. It is supremely frustrating to see. I would love to see a sequel where the main game of base building was the actual focus. Where things are rebalanced around that central premise and exploration is done better. Where enemy pathing is more predictable and progressions is not quite so linear. But despite all that, the 10 hours of peak content and the 20 hours of good content I got are still well worth playing this game for. Maybe as more community levels get created some true gems will draw me back in, but for now I guess I am satisfied enough.
