Reviews
Game is worth it for survival mode alone, However campaign is a mixed bag, heavily lean toward 'No'. Hero mission is waste of time, a snorefest, most of the time, on highest difficulty its just slowly killing thousand of walker, no active skill, only auto attack and consumable, there is no variable in the hero mission. Once you take tech, you cannot respec. I know its for challenge, however just make it 'final_point - respec_amount*x%' is that so hard? I really like the idea of meta progression in the campaign, too bad the dev intentionally made it feels bad to replay it with the inclusion of hero mission.
I love this game!

非常good
Good game
很好的游戏使我的聚集地被感染
The lack of save in game made me lose several hours of gameplay, you play for an hour, a wave break inside your homes and is a snowball to defeat, as I have limited hours to play this lack of save broke the game to me as I don't have dozens of hours to waste on repeating from scratch. Overall the game is actually good if you don't mind losing a dozen of hours on repeating the same mission
A good game.
