A strategy game with a new kind of enemy, Calyx puts you in charge of a space mining outpost, locked in battle against powerful plant-aliens. Build your base, gather resources, assemble your forces, and take on the Calyx. With only an out-of-date AI for company, can you survive?

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 Sep 9 → 1/day in the week after.
Reviews, worldwide (the counter carries no country): 1.29/day in the week to Jul 24 → 1.86/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.
About

A combination RTS and base builder with a brand new kind of enemy, the Calyx are a group of powerful plant-aliens that, left unchecked, quickly spread to control swathes of the map.

As the only remaining occupant of an Avaris Corporation deep-space mining vessel, you’ve arrived in orbit around a barren-looking planet. While you’re trying to get over being frozen for more than a century, you’re dropped to the surface as the ship’s AI outlines your Ore mining targets.
Build a power network, set up Harvesters and refine Ore before sending it to orbit for Credits. Build walls and turrets to protect your base. Deploy tanks and artillery to push the Calyx back before it gets too strong.
Balance your base’s energy requirements carefully to avoid vital defences being down on power.
Secure rare deposits to improve your mining and military capacity. Connect to booster buildings for additional power, mining and healing buffs.

Will you establish a strong defence, or attack the Calyx before it spreads too far? Dig in and build a massive force, or adopt a mobile and nimble strategy? There are many ways to defeat the different varieties of Calyx. Start your base wherever you like, experiment and develop your styles of play, and learn to cope with different scenarios.

Protect Data Archives to gain Research Points, and use the tech tree to unlock and upgrade more advanced units and buildings. Unlock the Inferno flamethrower and watch the Calyx burn! Build the Unit Workshop and manufacture the Goliath, a massive, multi turret tank, and boost its speed with hover technology. Unlock Orbital technologies and fire a devastating laser beam from orbit.

Protect and power communication arrays to access the corporation’s deep space network. Scan the Calyx roots to learn more about how these hostile lifeforms function. Discover new and dangerous Calyx variants as you battle to gain control of the planet and try to find a way home!

Sorry throws up a error message and it wont even let me play it
If you like creeper world this is your game!
I'm quite enjoying the additional goals that unlock the upgrades - replaying the levels when you are further up the tech tree makes them a different game, going for speed rather than just survival etc. These challenges are well-designed and quite rewarding!

以前的版本是好游戏可以前期用各种战术也可以后期巨型单位爽割草。最近新出的海军版本敌升我降自己方不加强不说还削弱,敌方到是感觉是所有植物的加强结合体,节点能放鱼雷,能出超硬小虫子基地满改旁边穿过去一只都打不掉的那种,小虫子还能无视防御塔去直接偷后面的建筑……科技树新页面一个海军升级也没有,感觉海军是脑洞大开突然硬加的一样,新页面解锁的大激光车在新版本也很鸡肋一炮打一只海军小虫子一截血只能最后打其他岛用一下,基本强制全面防御拖入后期,后期也是强行换血,感觉毫无诚意的版本!具体就是海军单位几个又弱又贵又鸡肋,毫无科技升级还不得不出,战列舰主炮副炮打小虫子都是挠痒痒打基地射程没有别人远强行换血感觉还没壁垒(陆地小坦克)好用,海军加血只能加一个还很慢射程很短,小机关枪船好像威力挺好的但是其实也是炮灰单位只能换血,对了,海军还没有防御塔,完全没陆战的爽了打无语了,希望制作组能改一下
Fun little game. This has great potential. I am glad to support the early access period
Can't say what it is but this game is very addicting. Maybe its that simple map painting idea turned into a RTS. The Calyx are such a unique enemy type too. Refreshing to find a SciFi RTS that's both simple to control and doesn't just throw the cliche horde of bugs or Orcs at you. Either way I've already got my moneys worth and I check updates regularly.
Really fun RTS base builder. Can easily lose myself in the levels for hours. The new naval content in the playtest has been great to play around with.
1. 게임이 너무 느림. 캠페인만 하는데, 매 판마다 업그레이드가 리셋됨. 2. 경제가 골드와 광물로 쪼개져있는데 덕분에 자원의 충당 속도가 너무 느림. 3. 정석적인 조합으로 천천히 밀어내는 것 외에는 공격의 수단이 전무함. 어떤 스팸이나 속도전 같은 건 시도조차 못함 4. 포가 쓰레기. 너무 느리고 사거리가 짧고, 위력도 없음. 존재의 가치가 없음. 근데 안쓰면 존나 힘듦. 5. 모든 유닛이 비쌈. 업글도 개비쌈. 이게 2번 문제랑 맞물려서 매판마다 존나게 느린 게임을 해야함.
гарна RTS :)
Its a fun little game. Building up your forces to slowly push back against the Calyx is quite fun. The missions do get repetitive but you can get about 20 hours out of it easily. Or a lot more if you like to replay missions on harder difficulties. And there are more missions to come as well becuase the campaign is not finished yet. It has tower defence elements in the early game and then you slowly build up and tech up and go on the offensive. What I really loved is the unit formations. In other RTS, units just blob up randomly. Here, you automatically get short range units in the front, followed by artillery and then repair units in nice little formations. More RTSs should implement this. I played just after the Leviathan update when the game was quite hard. But some people were whining about not being able to build on beaches etc. so they just released a patch which made the game easier. I dont think it was needed as I managed to finish every mission except one in my first attempt. I can see myself going back to it to finish the campaign when they add those last missions.
