Reviews
Simplesmente viciante, misterioso e difícil ! Procuro jogos semelhantes para jogar sempre, esse é definitivamente um dos meus jogos preferidos de RTS. Desafiador e estratégico ! Poderia muito ter uma continuação.. 10/10
Muito bom
Good game with good animations, you can pause it like an RPG game and to try to avoid getting eating by humongous hordes of infected and zombies while you thrive to survive in large maps. You have waves of hordes from time to time and some infecteds are very hard to kill.

superb game
A great game for us OG command and conquers vets. If you are one, this game is for you....you're a real one.
Good game bneed a second part!
No lo eh terminado, pero que jueguito del bien
好玩爱玩可惜没新作了
One of the best strategy game i have played. Challenging especially at first, but super rewarding. Definitely worth recommending.
I cant express enough how good of a hidden gem this game is. Its borderline edgy and goofy at the same time yes, but the dieselpunk/steampunk themes in the buildings and technology justifies itself is so damn beautiful, I just wished that the portraits of both zombies and units where not that... goofy, and the voice acting is kinda not tooo great... But nonetheless, the games is a general 8/10. If you like strategy games give it a try, its going to fry your brain a few times
