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.

好玩爱玩16200
Juego muy versatil, es una combinación entre un tower defense con age of empires pero con un estilo steampunk y obvio con los zombies, quizá es de los juegos que mas horas le he dedicado, como quisiera que le dieran mas actualizaciones
一段不玩再玩无法启动,点开始游戏然后没反应,继续点还是没反应,所以我买了游戏只能玩一次?

最近几年玩过的最能打发时间的游戏,小型游戏的经典
Love the game, I would definitely recommend for any fans of RTS. I wish it had more of an expanded campaign though.
