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): 7.71/day in the week to Aug 22 → 10.57/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
Forge your empire in the world of ants, building extensive nests and managing an intricate hierarchy in a way that puts the real-time strategy genre under the microscope. Control a variety of warrior ant species in intense battles, command your workers to build and supply an ever-expanding base, and protect your queen at all costs while navigating the unique threats and opportunities of the insect world.

Hundreds of warriors clash in a melee of gnashing mandibles as formic acid artillery fires overhead. Nightfall has come and the last of the workers are rushing back underground, dodging beetles to deliver food to the nest. The stockpile is empty, and without more, reinforcements will not hatch for the ongoing war between the duelling Empires of the Undergrowth.
Starting from a central room hosting your queen, order your workers to develop and optimise your nest – a vast network of store rooms, nurseries, and hallways. Dig through a hex-based maze of soil and bedrock, seeking food and fending off other underground dwellers.
Push beyond the confines of your nest to see what the world above has to offer – with seeds, nectar, fungus, other insects, and even amphibians on the menu, there's plenty to choose from, but each food source comes with its own strategic tradeoffs and challenges. Will you venture forth and fight off the ladybugs that eat and deplete your source of renewable honeydew drops, or do the surrounding nocturnal creatures present too much of a risk for your fledgling colony? Each decision you make has a ripple effect that can doom your colony if you aren’t quick to react to evolving circumstances.
Manage a multitude of species with different attack patterns, natural weapons, and evolutionary paths to tackle the particular dangers of your current biome. Nighttime sorties are at times essential as you look to secure food supplies, though unsuspecting ants might fall prey to the dangers that lurk after sundown. Come morning, you’ll find yourself competing with other ant colonies instead, entering enemy nests to attack their queens while defending your own. Prepare to operate and coordinate simultaneous war efforts across multiple underground and overground maps as your threats and opportunities change with each passing moment – there’s no single path to domination.

Workers scurry in from the surface. Few have returned, but they carry valuable sources of food that will help reinforce the front as a new wave of warriors pour forth from the nurseries, eagerly following the scent of pheromones that tell them where to go and what to do en route. They are the last bastion of the colony, born with a singular purpose – hold the line!
Design and organise multiple nurseries and assign them individual pheromone groups, with each pheromone group taking orders through the placement of pheromone markers, adjustable rules of engagement, and context. Learning to navigate the behaviours of your ants, as well as each species’ strengths and weaknesses, is integral to securing success.
Each pheromone group can be specialised on the fly, told to exclusively collect food, partake in combat, or do both – the right decision can turn the tide of battle. In desperate times, when the colony is starving and new eggs have stopped hatching as a result, will your warrior caste focus on gathering food at the risk of being picked off by aggressive enemies en route? Or will the soldiers divide into escort groups for your remaining workers, ensuring survivability at the cost of overall efficiency elsewhere? Don’t forget to keep at least some workers at the nest to dig, build, and maintain the placement of eggs, to ensure the survival of your ant economy.
Each species of ant presents its own set of strengths and weaknesses on the battlefield. In special game modes where multiple species can be raised in the same colony, your decision to raise and upgrade one or the other will completely change the way you do battle. Trap-jaw ants fight in melee, occasionally leaping back to replenish lost hitpoints. Leafcutter majors fulfil their natural role as protectors by drawing enemy aggression onto themselves to give allied ants an opportunity to flank, regroup, or escape. Wood ants can evolve to fire formic acid as long range artillery or in a more rapid, straight line. Find synergies between the multitude of natural strengths and weaknesses of each species, and prepare to defend against them when warring with rival colonies.
Your enemies are equally varied – apart from other ant colonies, you’ll engage in combat against arachnids, amphibians, crustaceans, and a wide variety of insect species. These powerful and often (comparatively) gigantic creatures present a unique threat to an unprepared colony, and only superior tactics can overcome them. An envelopment manoeuvre can circumvent the adult devil’s coach horse beetle's stunning spray, while tactically isolating and overwhelming hermit crabs one by one will bring their demise faster than they can hunker down to heal.

Victory is certain! Reinforcing troops arrive in the nick of time, fearless in the face of the horrifying abomination before them. Today the sadistic scientist has blended hermit crabs with scorpions into a terrifying new threat, but the colony has evolved wisely after experiencing such unnatural foes before. After a protracted battle the fearsome chimaera teeters on the brink of collapse, but a new foe arrives on the battlefield – piercing through the skies above, the hand of some strange being comes down to crush half the reinforcing troops, and from the great beyond the scientist lets forth an evil cackle. The tide has turned once more…
Apart from the classic RTS skirmishes against the AI and unique seasonal challenges, Empires of the Undergrowth also features a narrative-driven campaign mode. Follow the simultaneous progress of a lab experiment centred around the mysterious Formica ereptor gene-thief ants alongside a documentary series that explores the various species of ants in their natural biomes. Earn resources through successful documentary missions to upgrade your persistent lab colony and evolve according to your preferred playstyle as you put your ants through a multitude of brutal tests conducted in the name of ‘science’ – but not all is as it first seems…

Excellent game! Intriguing to learn about ants. Helped our little one (8) to completely get over her fear of ants. Lots of fun for dad, too.

Good game but important issue with Steam Deck. There is a bug where you can't play certain story missions because to start them you need to select a particular option that just does not work with controllers/Steam Deck. Devs are apparently aware of the issue but ut's not be fixed for several months.

What a hidden gem!! 9.5/10 This game is FULL of bugs! All sorts of Bugs, some nice bugs like aphids, and some nasty bugs like emperor scorpions, and a supreme bug... but I will let you discover that one ;) I have played many different RTS games, and this is one of the BEST I have played in a VERY VERY LONG TIME. I stumbled on this game and I was initially hesitant, but damn am I really glad I bought this game. It holds a somewhat unique style, and a rather comical and entertaining story. But saying that, the one game that this remind me of, and I dare say may have drawn inspiration from, is Dungeon Keeper. Which is not a bad thing by any stretch of the imagination, Dungeon Keeper is an absolute work of love and art. If I were to rate this game for what it is and the size of the dev team (3 people as far as I know), the thought, care and detail that has gone into this game. I would have to give it a 9.5/10 I being a veteran gamer of 30 years gaming, am a HARSH critic of games, so this rating I have not given lightly or without thought. My suggestion when playing in terms of the difficulty, choose Easy if you are after the story mainly, and medium-hard for a challenge, where you likely will need to replay the occasional mission and Insane if you just like to loose
Це незвична стратегія що мені зайшла Плюси - текстова українська локалізація - місії у форматі документалки - цікава прогресія(хоч й не сильно різноманітна) Мінуси - не можна зберегатись у місіях, тільки у основному хабі
地下蚁国是一款与众不同的RTS游戏,它是一款拟真的蚂蚁游戏,不像是传统的RTS,它模拟了真实蚂蚁的生长,在现实中蚂蚁可不会点一下就出现,蚂蚁需要时间来成长,而且生长期间也需要食物这一点也有很好的体现,你要建造蚂蚁的孵化方格才能孵化蚂蚁,每个孵化方格只能有一个卵,在孵化后你的工蚁会放上一个新的卵,这看似很麻烦,但这独特的爆兵方式让你的蚂蚁在死亡后能够第一时间孵化出新的一只,当然这游戏不是没有缺点的 缺点:只有你玩了才知道,在科2眼里“30=40”,“魔鬼隐翅虫=小”!这还只是第一场实验!还有,从火蚁章节开始极限成就就不是人做的,5.2“掠夺掠夺者”要从行军蚁手里抢回200个食物,是200个不是200点!极限已经很难打了,黑行军数值更是爆炸!玛塔又贵。5.3白蚁关卡都没做完就搬上来了,音乐白天用的是3.1,晚上是1.1,前两章好歹是还有自己白天的音乐,这关根本没有!那个防蜘蛛恐惧症也是逆天,部分蜘蛛在拉满之后也会漏出腿,官方是不知道若隐若现的东西才最可怕吗! 优点:除了独特的玩法外,地下蚁国前三、四两章的音乐绝对是百听不厌的,而且优化这块是除了5.3都好到爆看到最低配置你就知道了,但因此画质没有好到哪里去,不过因为上帝视角的缘故所以也够看。 总之如果你是一个喜欢全收集的玩家,就赶紧走,这成就真的会打得你怀疑人生,但如果你想要欣赏音乐,或者是喜欢看着蚂蚁的话那就可以入手,毕竟简单难度是真的简单啊
个人比较喜欢
ngl this game is tuff for all those in the future thinking about buying this you should go for it i have nothing else to say about this game its just overall amazing
太好玩了,好玩的我直接给我养的蚂蚁配了
This is the single greatest game about ants out there. If you like ants even slightly and own a steam account, buy this game. Music is 10/10 and narrator's voice is hot.
