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.

Un excellent jeu, particulièrement prenant, avec une super bande-son. Je le recommande vivement. Dommage qu'il n'y est pas eu de suite ou de DLC.
优化很好,十三年前的电脑也能玩。僵尸种类很丰富,士兵也很有特色。而防御塔就只有四种了。要是有类似于死神和路西法的防御塔就好了。威力再提高点。死神的火箭筒威力还没英雄的手榴弹带劲。

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.......
seriously addicting defense game. loved it, will play again.
チュートリアルが無く、遊び方が分からない
Game good, zombie bad
I enjoyed the game, but my progress is gets lost with some sort of saving error with the game. Kind of ruins the experience when the game loses my progess.
сложно
专门充加速器来发差评,傻逼作者,你是不是以为你特别会做关卡,抵挡波次没有加速只能硬等。没有读档功能是最傻逼的,这意味着你玩半个多小时一个多小时一不留神就被僵尸后入了,然后你要从0开始继续玩,这个傻逼游戏初期又贼几把漫长,草泥马的。我从未见过有任何一个游戏失败带来的负反馈这么大的。♥♥♥♥
В игре тупейшая механика сохранения. Если твою базу вынесли, то игра объявляет о провале миссии и тупо перезаписывает мое сохранение где у меня еще дела шли хорошо. Нет разных слотов сохранения миссии, это про жесть, у меня нет слов. Это худшая стратегия в которую мне приходилось играть.
