这个赛道很特别,希望能坚持下去,游戏虽然有些bug,但是很好玩
Unironically one of the best zombie strategic simulators ever made.

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 2,402 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.

Unique very awesome game that in a year will be one of the coolest games ever made. Easiest way to sum it up would be its like if the Prototype series was an RTS like Men of War.
Awesome game, the idea and functions are great, real time action and constant fighting.
LOVE T
nearly everything i have ever wanted in a zombie outbreak rts but ehat i think would be a great addition would be something like a new subsystem of information spreading about the outbreak such as flying helicopters to spread pamphlets about signs and symptoms which could work to both slow spread rate and have armed citizens forming militias like they did a while ago. maybe add some extra tactical decision making in deciding whether to assist said millitias with supplies and guns or simply focus on evacuation. the bigger the civillian resistance the more survivors flock to the area attracting zombies more and more as it grows. making it a balance of how you split your resources between building C.E.R.C units and suppourting the civilian groups
좀비 아포칼립스 지역에서 민간인들을 구출하여 헬기로 수송하며, 사방에서 몰려오는 좀비들을 진지구축과 다양한 병과와 기갑에 무기커스텀, 포격지원, 공중지원 호출등으로 어려움을 극복하는 맛이 있는 신개념의 RTS게임입니다. 아직 한참 개발중인 얼리억세스 게임. 꾸준한 업데이트로 나름의 세계관을 차근차근 구성하는 중인듯합니다. 2026년 8월 기준 experimental 버전에 힘을 쏟고 있는듯 합니다. 기본공개 버젼은 그나마 한글화가 되어있기때문에 튜토리얼 느낌으로 플레이하시다가, 조금 더 확장된 게임시스템을 원한다면 experimental을 영문버젼으로 플레이하시는 것을 추천합니다. 초창기부터 1년에 한두번씩 플레이하는데 매번 꾸준히 발전하는것이 느껴집니다. 아직 얼리억세스이지만 당장도 충분한 플레이타임을 보장하며, 충분히 즐기신 후 가끔 RTS 당길때 다시 깔아서 하면 오래도록 즐길만한 게임 같습니다.
fun zombie infection game like small tower defense but you are a steam roller > :3
over hated ganky glitch but and i tried to extract suvilians but it not possible combats good but games super laggy if you dont have a op pc
