I cant really recommend it - its fun but its not a good RTS they have too much in depth infantry tactics and menus to make it a good RTS of like actively fighting the enemy. like you need to command a chopper to land, then command infantry to load to the chopper then command the chopper to take off. in a normal RTS, pick infantry, click on chopper, chopper lands infantry get in and chopper takes off on its own. the chopper should default being up in the air - not landed, landed means dead or loading, the UI is TINY TINY TINY, i dont even see what im building and all the buildings have very specific needs, you HAVE to have a generator near the thing requiring power, or no power, why am i being an electrician? i wanna shoot zombies. very cool idea but not executed well ok to answer the dev in more depth- i have played a LOT of RTS games since i was like 7, what i have found is that if you have in depth infantry and unit stuff you should have very basic buildings like company of heros 1-3 or dawn of war 1 and 3 (they produce things, or are designated upgrade buildings or you need building A to build building B to get building C) OR you go very basic infantry with complex buildings like star wars, 8 bit army, age of empires (you throw tons of infantry, tanks and aircraft at each other and nothing has any value besides your base) or the third type which is a mix of both like starcraft and all the command and conquers (buildings make stuff like infantry or tanks, only 2 or 3 buildings produce said units, the rest provides a small purpose on its own like power or more money but easily replaced if lost) again i like the concept of the game ( id like more proper tanks like abrams for late game stuff or play as the zombies so you can understand the tactics and strategy better) but ill never forget the tutorial i had to watch from a youtuber where he said "you dont win you just contain" so to me its an oversight of not really an RTS its more like a wave defense with too much stuff in the background of weapon loadouts for my soldiers where i can have 4 squads of dudes ALL WITH DIFFERENT WEAPONS and theyre all dots down on the ground and im not gonna tell who is who at a glance unless i open a new menu to see who has what. instead of this squad i trained only has machine guns, cant shoot rockets and this other squad is all rockets no machine guns so i know rocket guys cant do hordes but handle big tanky enemies but machine gun guys are the opposite - good crowd control but minimal damage to large enemies. KISS keep it simple S

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

This game has come so far, it’s getting daily updates and has such a great community and EXTREMELY active devs. Gameplay is challenging, albeit buggy at times but I play on the experimental release where bugs are bound to be more frequent. The bugs don’t stop me playing for literally hours at a time, and if you enjoy RTS in a multiplayer setup where some of your team manage base building, some manage forward pushes and some like to be on the ground in first person fighting the zombies in an FPS style game, then play this. It’s all possible!!
You proved you could make a good game that was fun and enjoyable, but you decided to scrap the system and start from scratch, coulda just made a whole new game...
refunded cuz no tutorial devs throw u into the pits of hell and expect u to be born knowing what 2 do
I have to say this is one of the very few games I regret buying. The idea is great, the draft is decent, the execution... oh boy. I never had the game run smooth. It's laggy, janky, crawls at times. Bugs and bugs everywhere and I'm not even talking about the zombies. I've had the game for quite a while. I come check if it's better, get pulled in for a couple hours and then give up because it's not really that fun. Still compels me hope it's better, but never is. Not to mention the devs don't seem to be very nice people. I've had one workshop post about a possible issue or bug and the reply was not very elegant (and I'll leave it at that). I just gave up reporting stuff. Haven't played the game in over 6 months and I don't think I ever will again. I was going to install it again today but just reading the past updated and past reviews and... nope! But hey, they have my money, don't they? So I'm the idiot here. I really, really need to give up on Early Access games and it's games like this and people like this that makes the very interesting premise of Early Access crumble from distrust. Oh yeah, and game's not finished but they make stupid skins DLCs? That's not good. They are either trying to cash out and run, or scrambling because they are running out of money. Either way, game's flipped.
When this first came out I loved it. As time has gone along I cant even play it without it crashing in the first 10 minutes of play.
我不知道这款游戏还要更新多久,就如今的状态我无疑是非常愤怒的 首先作为一个丧尸类rts游戏,游戏的大框架无疑是非常优秀的,但是缺点是我难以游玩 1.居民撤离速度如乌龟一样慢,你敢信我在自定义的情况下,在没有丧尸的情况下,三个小时也就撤离了五分之一,在此之间撤离点已经拉满了,咱就是说为什么一定要空运,既然是岛为什么不增加海运。 2.你游的大多数高楼楼顶都是可以上去的,我想问那么大的楼顶,为什么不能建造建筑物? 3.最搞笑的来了,我不知道是bug还是我不会玩,侦查直升机半天找不到感染者建筑物了,你要是二战冷战我不挑你的理,都现代了找个建筑很难吗,你游的战争迷雾我强烈建议直接取消,不只是建筑,哪怕是一个桥,丧尸来了都能突脸,战争迷雾不会搞就别搞了。 4.你游的空袭机制,那么个小桥,现代航弹炸不烂,牛逼 5.零号病人纯纯数值怪,能不能换个别的模型和机制,5w的丧尸,直升机洗半天 6你游的武器系统比较多,但是我认为能高效清理普通超大规模尸潮的只有喷火器,你游的武器经常能看见丧尸来了不打,只有喷火器能在瞬间打出高伤害 最后,鉴于你游如此的效率,我不是最早玩的,但是这游戏好几年了吧,该打磨打磨了,别一直加新的了,哪怕是你多加几个模式呢,我说白了,你游玩起来真想编辑器吧,你又不是几百的游戏,想做成啥样?????????
doesnt run good on my laptop i refunded
this game has a nice concept and i hope the devs keep up the good work (there were some bugs and freezes but its early access)
Ambitious but crap, had this game for several games now and with each patch it just seems to get worse.
