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 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
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.

No regionalised controls in big 2026, was this game made by toddler that never programmed?
Im sure there is a good game beneath here, sadly the building as often very clunky and unprecise making it more of a chore. Additionally there are still game breaking bugs it seems. Im straight up soft locked in a campaign mission and cannot continue. Sadly it is after the refund mark

After playing They Are Billions, I was hungry for more horde defence games with solid base building. Cataclismo has absolutely sated this hunger, which it owes mainly to its intricate building system. Rather than putting down whole buildings and wall segments like in TAB, you can place individual blocks that make up your defensive structures, like walls, towers and battlements. With these defences, you have to hold off multiple waves of incoming horrors, aided by various infantry types. This simple mechanic creates immense emergent complexity, where the way you connect the blocks, where you place them, how you account for troop ingress and how you lay out the various traps and buffs are all deciding factors for the efficacy of your defences. It all makes for a very fascinating challenge to lay out an optimal defensive line. Losing a mission was never frustrating in Cataclismo, because it feels like you just learned a lesson in what doesn't work, and you get to take that knowledge with you to the next attempt. Very enjoyable game, clearly well-crafted and very polished - highly recommended if you enjoy defence games.
Wanted to like this game but; The camera controls are absolutely horrible, not having full and free control over the rotational pan (instead you rotate the camera in like 30 degree increments) is insane. The voxel style is cool but makes it hard to tell what's what and what's going on.
拠点を守りながらマップを探索して新たな資源を見つけそれでどんどん拠点を強化して防衛する感じ ゲーム自体は面白いが雰囲気に全部りしすぎて色々不便で分かりづらい UI見づらい使いづらい、キャラぱっと見で判断しずらい移動もクセがある 敵も見分けづらいし何が来るのかよう分からんw 施設も似たり寄ったりで何があるのか無いのか判断しずらいマップに溶け込むので 建設がしづらい そのくせ制限時間は短く資源もガンガン入って来るわけじゃ無いので 施設に必要な資源をじーっと見ながらたまった瞬間ポーズしながら一個一個立てて そのすきに探索もしないといけない ゆえに楽しいゲームって感じより疲れる ※ネタバレあり あと時をさかのぼる能力があるんだがゆえに特にストーリーモードでは 後出しじゃんけんをして来る そのたび時をさかのぼり改善する、ストーリーとしてはすごい能力のように聞こえるが 要は相手の理不尽ムーブにセーブ&ロードを繰り返しながら対応しないといけないだけ しかもそれが前提だって事だ!!建設めんどいのに!!!マジムカつくww 物語的に主人公はこの理不尽をプレイヤーの私より何倍、下手したら何百倍もあじわっている そうだ… 同情通り越して鬱になるわ!!w 挙句の果てにムービと字幕まで分かりづらい!!!w 楽しく気がるにゲームしたい人や短気な人には向かない気がする 気になる人はド素人プレイ動画を見てイライラしないなら買えばよいと思うw
地形や防衛施設を自分で作ってユニットを配置するタワーディフェンス タワーディフェンスと言いながらもタレット的なものはなく自分で櫓や城壁を築きそこにユニットを配置して敵を迎撃する 他のタワーディフェンスとの違いは高さの概念だろう このゲームは高所からの攻撃はボーナスが付き壁も高く築くほど丈夫になる よくあるものだとワンボタンで設置できる櫓にユニットを配置するところだがこのゲームはなんと自由に櫓を組める、城壁城塞すらも構築できる しかしステージが変わるたびに城塞や防衛施設を一から手組するのがおそらく好みがわかれるところだろう 自分は手間がかかりすぎることにストレスを感じて途中でコントローラーを置いてしまった
Never played a base-building, tower defense game like this one, with such freedom of expression and creativity. I was expecting tougher, more intense missions, especially the Citadel and the Alta Perl. Those passed too quickly. The gamemodes add the missing difficulty, but lack the potential immersion. The art is beautiful. The touch of spanish is perfect. I feel like she's here whenever I listen to Iris' voice. Just finished campaign and will be recommending this to all my new friends.
Great game, mixes different genres in a refreshing and fun way. Take it easy and pause to make strategic choices, avoid it and panic your way to victory. Constructing bases is satisfying and the troop combat is quite fun too. Fortifications are quite weak and go down easily, some kiting and clever mixups are needed. Some obvious cheese has been fixed. At times the terrain feels a bit unforgiving. Do recommend!
this is not a super long game but this i would considered more forgiving then they are They Are Billions. if you general like base building this one is fun
3D版亿万僵尸,但是因为要搭建城墙,所以建造部分比亿万僵尸麻烦的多,尤其是封顶的时候,没有虚化城墙的功能就十分难受。 有蓝图功能比较赞,但是没有资源视角一键查看所有伐木场和矿场,也不能自动分配工人,所以运营方面就比较难受了。 天赋树和战役也比较短,然后天数也卡的很紧,经常运营一大堆,没出多少高级兵种,就靠着城墙和低级兵打完结束了 总体还是十分好玩的,有单存档也没有感染机制,所以玩起来还是比较爽的,就是搭房子太累了,转视角和卡位太耗时间。
