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): 0.43/day in the week to Aug 25 → 0.57/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 2,400 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.

Что можно сказать после первых 6 часов игры Играл на максимальной сложности В целом довольно бодрые забеги на 5-10 минут с разными миссиями. Разнообразия хватает. Сложность повышается в целом плавно в дальнейшем это компенсируется прокачкой Настройка перед боем позволяет собирать комбинации которые нравятся именно вам Вариантов не то , чтобы много , но вполне достаточно для игры часов на 10 Советую сразу добыть пару генераторов и раскочегарить производство на максимум , чтобы не задерживать глобальную прогрессию , на максимальной сложности ресурсов более чем достаточно , чтобы к 6 часу производить по 10 генераторов в ход и особо не испытывать проблем с ресурсами Со скидкой 50% игра с лихвой отбивает потраченные средства в плане удовольствия на несколько вечеров Дополнено после 15 часов Башня полностью улучшена и начинается гринд чисто получить все улучшения, по ощущениям затянется часов до 30-40 игры . Но сложность игры также понемногу возрастает , однако реальные проблемы пока могут доставить только сложные рейды ( средние и простые пролетели на раз часу на 12м игры.) если идти по нарастанию сложности миссии кажется простоватыми Дополнено после 28 часов Вот и завершена сюжетка - при том , что последнича 5-6 часов я только бежал по кратчайшим маршрутам до миссий основых, дальше челенджны и выбивание ачивок . А дальше возможно пара миссия на скилл

fun roguelike tower defense with meta resource gathering, research trees, and upgrade options
-
内容重复度较高.玩几把就不太想玩了.希望多出点新玩法.
Concept is fine but it gets very repetitive pretty fast. I'm used to roguelikes so its not like the cyclical nature is a problem for me, this just doesn't do it in a way that is entertaining. Crank the difficulty up and you're still sitting there bored waiting for the level to end. Some levels require a tiny bit more interaction but its just ordering your mining thing to move and then watching it inch across the screen. It does have some story missions that break up the monotony but you have to do a bunch of the repetitive missions in between. Thats just the gameplay though, the voice acting is also awkward and the writing isn't the best. If you grab it on sale you'll probably get enough out of it to be worth it but I'd never recommend this at full price.
sehr kurzweilig und macht richtig spaß.
Un juego muy frenético y adictivo. Comprendo que puede que sea distinto a los típicos juegos tower defense, pero su acercamiento al género me parece el más creativo y llamativo. Me gustaron los gráficos, el sistema de progresión y mejora me parece raro, pero le pillas el ritmo. De sus pocos puntos malos es la introducción, la historia y los chistes, aunque con suerte lo puedes desabilitar. El mejorar tus herramientas y héroes se siente satisfactorio, y el bucle de juego me parece muy bueno, aunque recomiendo no jugarlo demasiadas horas seguidas, o te quemaras muy rápido. Me parece justo su precio, eso, seguire jugando y si veo alguna otra cosa, lo añado. Edit: Termine el juego. Recomendaciones si haran una segunda parte: Añadan tutoriales que expliquen bien como funciona la mecánica del fluido y las dinámicas del terreno, es aleatorio y molesto que te salgan las explicaciones de la nada en la carga de pantalla. Siento que faltan más modificadores para variar la jugabilidad, como usar una mecánica de fluidos a la inversa, como un geiser de ácido, y tener que cambiar la posición de torretas y la disposición del terreno para desviarlo. Sigo sintiendo que es un gran juego, pero si se arreglan esos detalles y se explotan aún más los puntos buenos, la rejugabilidad seria abrumadora.
ワラワラ群なす下々の者達を衛星軌道上からいたぶるのが中毒性になるゲーム あなたの心にムスカを宿しているなら買い 機銃掃射で ボムで 爆撃機で 地雷で まるで敵がゴミ…いや汚ねえ花火だ 熱中する程の熱さは無いがマインスイーパーの如くだらだら続けられる。 ストーリーは20時間程度でクリアしたがミッションが短いせいで体感40時間プレイしたかのような気になる。 クリア後も未探索のイベント地やミッションの連なるレイド(3か所)に未獲得の成長要素が加わり、エンドコンテンツは豊富なようだ。 ミッションの種類は5つあり、これにストーリーとレイドが加わる。 ミッション中、時間経過で敵の攻勢が激しくなり、クリアする頃にはアップアップしながら任務成功の表示を見ることになる。まずは広く生産施設を守り、終了間際はベース近くに撤退し亀のように耐えるのだ。 難易度は4種類を任意で選べる。イージーからエクスストリーム(ストーリークリア後) 始めたてはイージーでも厳しいが。成長して装備も持ち込み量が増えると盤面を上手くコントロール出来て気持ちが良い。そうなると結構面白いアイテムがあって、玩具をいじるような楽しさがある。機銃掃射もそうだが、液体の上に建てるとドンドン兵士を生産する建物とか。 だらだら遊び、コツコツ成長を楽しめる良いゲームだ。
Surprisingly fun, although some game modes are more tedious than others. And yes, the progression is too grindy. But the increasingly challenging modifiers make you want to keep up with your upgrades, and that was enough for me. The variety in turrets, heroes, maps, and modifiers keep things interesting, too. The optional "raids", in which you go through a series of missions and persisting upgrades, are a fun addition. They let you see how far you can really push your tactics, and they allow for combo's you won't see (much) in singular missions.
很好玩的塔防布阵游戏,适合休闲长期玩耍!
