About







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.

남이 하는거 보는 것보다 하는게 더 재밌는 게임 색감 똥꾸릉내 나는게 무슨 재민가 싶지만 몰래 온 손님 때문에 빡쳐서 그런건 생각도 안나는 게임
但凡更新一下储存读取功能就更爽了,每次从新开始真的很恶心。制作组跑回来救一下啊。
Best of the game for me

I keep coming back. Great game. As easy or as challenging as you want.
Unforgiving and boring
Divertido e duro.
Игра - крутая, интересная. НО - долгая мета-прогрессия в компании; и(!) отсутствие сохранений (вернее, возможности сохранятся), из-за чего один косяк, приведший к поражению = начинай с начала Но игра правда интересная, советую
This game is great if you like a challenge with your city builders, i like rts and city builders but they never scratch the itch on both sides for me this game does
I don't agree with people giving the thumbs down because they don't like the campaign. I agree with them that the campaign is not great, but that's just one (small) part of the game. 99% of this game (and fun) for me has been just a map, a couple of buildings and BILLIONS of zombies. So big thumbs up from me.
pedazo de juego, si te gustan los rts o los tower defence este juego es espectacular.
