Great game, it still feels a lot like what it is: an early access, but i really liked the concept. Hope they improve how units move and position themselves with the environment, cuz it feels a bit silly to have troops just standing there instead taking cover like in Company of Heroes.
For what it is, it's good, but things such as armed civilians coming out of any building and destroying your infrastructure because it's just a little overcrowded is scuffed. It would be one thing if you could disperse the population or have mechanics that crack down on firearms ownership as a result of their destruction, but I can't manage a war with spitting zombies, zombie crows, and juggernauts while i have to worry about every building potentially ready to pop. There's other peeves of mine when playing this game, such as AI pathfinding and that there is no tutorial, but for what it is I would recommend it in this state, especially since the devs are actively improving it.

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 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.

망겜 게임성은 볼 게 없음 불편한 ui, ux 좀비 같지 않은 ai - 감염지에서 가장 먼 도시에 전초기지 지었는데, 중간 도시 다 무시하고 달려옴 허술한 번역 - ai 번역이라도 해라 흥할 수 없는 이유만 가득함 그런데도 불구하고 이 게임을 산 이유는 하나임 컨셉 포스트(좀비) 아포칼립스 장르는 수 없이 많지만 좀비 아포칼립스 직전을 다루는 rts 게임은 없음 (있으면 추천 좀..) 그리고 좀비 아포칼립스에서 군대는 항상 이미 무너진 상태로 나와서 군대로 좀비와 싸울 일이 없음 하지만 이 게임은 트레일러 보면 알 수 있듯이 항공기, 전차, 장갑차 등 나와서 좀비와 재래전을 펼침 진짜 이 컨셉 하나보고 사는거임 게임사에서 버렷냐? 그건 아닌듯 옛날부터 계속 지켜봤는데 업뎃은 꾸준히 함 원래 거의 버렷다시피 했는데 1년전부터 업뎃이 좀 활발해졌음
great game has a lot of potential just needs some time
If you can get past the jank, and lack of tutorial this game is so fun.
Great game once you get the hang of it.
Ideia de jogo muito boa, me surpreendeu. Ponto negativo, é que não fica muito claro como ser feito as coisas.
Pretty neat.
Güncel hali oynanılabilir, yeterince gelişmiş olmasa da geliştiriciler üzerinde yıllardır aktif şekilde çalışıyor. Single player bir süre sonra sıkıcılaşabilir fakat oynayacak çevreniz varsa oldukça uzun saatler eğlenebilirsiniz.
Extremely customizable, complex gameplay, good graphics... I can go on and on. This game should serve as a benchmark standard for modern RTS titles. Been playing for over a year, and every update gets better. Definitely worth a buck for the bang.
