Reviews
A different RTS game. Cool topic, nice mechanics, good storyline still somehow limited variety.
Great game. Will make you hate your life at times. But don't worry. It's YOUR fault when you lose.

if you like games like Age of Empires and zombie games, you should have already bought this game yesterday. it may not have the most realistic graphics, but it's such a fun game that i'm personally grateful for the simplistic graphics. it means i can install on pretty much any computer capable of connecting to the internet and it runs like a dream. i have over 2500 hours in this game and since i bought it i have been gradually working my way up the difficulty scale. at this point, i'm at about 13% difficulty in survival mode and still struggling. yes, there are easier difficulty levels which actually make this game pretty accessible across player skill ranges. but the customisation of difficulty means that you will likely have to keep trying to actually beat this game on harder levels. replay value is absolutely through the roof.

不能存档是什么傻狗设定
No mission surrender or restarting is criminal in a long slow paced RTS, especially when you get no rewards for losing a mission that takes hours of mostly nothing. Can be fun, but do not recommend.
Game is incredibly pretty. Love the graphics. and generally the controls are really really good. But overall the way it is structured is very tedious and annoying. If you start a new campaign, each time you play a mission and fail you get a mark that indicates how many tries it took. This is totally fine, not really any issue with this. But because of this, individual missions can not be saved in the middle of them. Progress is constantly saved like a roguelite or something to prevent "save scumming", which is kind of ok in a defense game, like I get it. But what this ends up translating to is a very punishing and just straight up not fun gameplay loop of spending 40 minutes clearing a map, learning mechanics, and being within an arm's length of the mission objective, just to have 1, literally 1 zombie show up somewhere randomly on the open side of your base that your multitude of patrolling army just didn't see for some reason even though you made SURE to cover it, and you constantly pause and start and check the minimap and every inch of your base to make sure they are not getting in. And then literally one zombie attacks some fringe hovel or something that you have and now you have an uncontainable outbreak in your base that totally wipes your mission progress. And now the only option for you is to play the mission over and go through all of the same tedious steps as before. Most RTS let you save and load which means you can be in the middle of a mission or have some sort of checkpoint to play from instead of having to sit through the buildup phase if you miss ONE tiny little red blip anywhere on your minimap. I know that this is a defense game, and I've been playing RTS since 1998 (Starcraft) so I don't mind punishing controls and fights, but this is so punishing in such a not fun way that I want to love this game so badly, but it's just NOT fun to build up a city for 30+ minutes or whatever and it's all undone because you missed literally 1 zombie. There is no comeback mechanic or controlling units in a fancy way to get back into the game. You just die to the infection snowballing and have to redo everything you just did.
They Are Billions — це коли один пропущений зомбі з'їдає твою 4-годинну роботу, а ти замість того, щоб видалити гру, з посмішкою запускаєш новий матч. 👍 Рекомендую (Чистий адреналін)Ця гра — справжній цифровий мазохізм, від якого неможливо відірватися. Я просто хотів розслабитися ввечері, а в результаті до п'ятої ранку будував стіни й рахував кожен шматок заліза.Чому вона чіпляє:Ціна помилки. Тут немає швидких збережень. Якщо десь у кутку карти один зомбі непомітно просочився через твою оборону — за дві хвилини вся колонія заражена. Це тримає в такій напрузі, якої я не відчував у жодній іншій стратегії.Масштаб фіналу. Коли на тебе суне справжній мільярд мерців, а твої кулемети та солдати ледве встигають перезаряджатися — це чистий кайф і мурахи по шкірі.Почуття тріумфу. Коли ти нарешті виграєш карту, яка душила тебе кілька днів поспіль, відчуваєш себе богом тактики.Так, гра жорстока й карає за кожну неуважність. Але саме тому перемога тут приносить стільки щирої радості. Якщо любите хороші стратегії та складні виклики — беріть, не пошкодуєте!
Queria muito um jogo no estilo de Age of Empires 2. Esse é o mais próximo que encontrei
1. 자원을 채집해서 모은다. 2. 열심히 발전한다. 3. 유닛을 만들어서 좀비를 잡는다. 4. 방어벽도 만들고 방어타워도 짓는다. 5. 잠깐 한눈판사이에 집이 터져서 좀비세상이된다. 6. 게임을 끈다. 7. 다음날 게임을 또킨다.......
