One of my favorite games ever, if you know siren's domain from town of passion you can see the difference between town of passion and zombies retreat but story is good enough to play it. Not my favorite type of art tho but the scenes make them work so can't complain at all. Gameplay is entertaining at some point but being griding at the begining could be tedious for some people. Fight is good the bosses are fine, nothing out of the blue and some times a little bit hard, if you wanna try it, you'll kinda like it
