“Surprisingly good time! If you like tower defense and you like old CoD zombies, this might be an enjoyable game for you. Higher difficulties definitely make you work for it, but if you can get a good enough base setup you can last for quite some time”
— a player, Steam review · 6 hrs played“SUPER FUN especially at the price point, i would give it 20 tbh. Its like old school COD zombies with wall guns, perks, and pack a punch, but also has (base building) not too in depth but enough to set up and make a stand. has special zombies and bosses but you can turn them off…”
— a player, Steam review · 20 hrs played“At round 20, the ability to turn stops working with a controller. This has been happening for over 6 months! WHEN ARE YOU GOING TO FIX THIS!?!? Used to be a fun game, but no point of playing now.”
