Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.

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): 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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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…

Reviews
小众 RTS游戏,以微观蚁群为视角还原昆虫生态,纪录片旁白搭配地底环境音效,沉浸感极强。看蚁群搬运、厮杀、筑巢十分治愈,犹如看壁炉篝火,能够入定。 关卡制闯关 + 巢穴永久养成设计合理,关卡收集蚁皇浆全局解锁基因强化。地底开拓、资源管控、对外征伐三位一体,战斗可编组托管,不用高强度双线操作,休闲挂机看蚁群运作或是手动攻坚都能获得不错体验。不过关卡内无法存档,长线攻坚关卡一旦崩盘只能整局重开,几十分钟运营成果直接清零。
The second leafcutter level with the soldier ants approaching pissed me off!!! 10/10 game

这是我的童年
Great gameplay, not only there are TONS of levels, you can play as ants, termites, and just play battle mode. Reccomened for all players who like commanding troops and making a colony.
这真的是一部我很喜欢的游戏,希望这部作品可以让更多人知道,我小时候就喜欢蚂蚁,现在也喜欢,等我经济独立之后我要好好准备养一窝蚂蚁,我已经想好了,就是大头蚁,我觉得不错,可惜地下蚁国里面玩家在养殖箱用不了,不过这也算是圆了我的一个梦吧,一个暂时还实现不了的梦,官方也很好,虽然热度已经上升了很多,但是仍然听取玩家的意见,不摆架子,愿意学习,这样的良性循环才是好的游戏开发者,早日开发后续剧情吧,我想看到更多蚂蚁和更SB的科学家二,今天玩了一天了,真的累死我了,等我过几天从学校回来,应该就可以把4.2和5.1过了,小的时候就看鲤鱼和小熙玩这款游戏,甚至连籽岷也玩过,当时就是没这个钱,也不知道怎么下steam,不然我就是最早玩的人之一,现在真的很疲惫也很快乐,在同类型的昆虫类游戏里面这是碾压级的存在了,其它的蚂蚁游戏都是建模粗糙没有创新还不真实,这完全是几乎完美的作品,如果资金和人才充足,我认为这将是一部风靡全球的作品,也让更多人喜欢蚂蚁🐜🐜🐜
看蚂蚁打架我能看一天!好玩!
Fun game. Slightly limited by the A.I.? in custom mode after beating the game though. Every custom game kind of devolved into just killing the other colonies for me. Still would recommend though. Will likely play again in the future but a bit burnt out for now. 7.5/10.
its a good game but needs multiplayer 8/10
plz快点更新吧太好玩了😭
ant kills stuff very well
