Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Sums Steam only; PlayStation, GOG, Nintendo publish no volume signal, so the true total is higher by an unknown amount.

玩法很有趣
i bought the game pre-release. I have still only played the survival mode over and over again. i have just died over and over again. its a learning experience but i have beat the survival game on every difficulty except the hardest one. nightmare. once you make a mistake the game is over and you have to start again with a new map. good luck its been pretty fun. i consider this one the most interesting tower defense game against waves of zombies.

heel vet, en erg diepgaand. Even voorbij de gedateerde pixels kijken en je zult zien dat het echt de moeite waard is.
Simplesmente maravilhoso.

Just fun!
Difficult. Very difficult. But once you learn how to construct your base, the pain gives way to satisfaction.
It"s a really hard game to play, that said it"s very fun to learn the mechanics, (you just have to get used to dying a lot) :D
отличная игра. играл в пиратку и решил купить
断断续续玩了四五年,只能说制作组跑路留下了的是神作,要是不停更新说不定就粪了(笑 好吧,说笑的,TABS这个游戏既是这个赛道的鼻祖又是巅峰,也是RTS在20年焕发的又一春;后续类似的游戏总是会缺点什么,要么是机制,要么是玩法。其实从噪音机制的复杂性上来说可以看到制作组其实很有野心,丧尸不可控的AI随机性又会切切实实地让每一把都会真正意义上的完全不同,从而非常上头,但是制作组赚足了钱就完结了,朴实无华地达到了现实的大圆满,那些可能存在的新奇东西都埋在代码里再也无人问津(悲 十分推荐RTS爱好者和回合制爱好者入手(自带暂停,可以算广义回合制),一杯茶一包烟,一个殖民地建一天(然后犄角旮旯的丧尸跑出来咬了一口建筑,开饭2分钟,笑)缺点是这个游戏没有存档机制、战役有又臭又长的英雄任务(还得捏着鼻子、为了解锁科技去打)、而且没有Mod能帮你补完这些,从这个角度而言可以称得上一句硬核。
