it was just some ok zombie game 5/10
edit: this was the same dude that blamed the sequel's cancellation on players who waited for a sale lol
also some of the bugs at launch were gamebreaking bugs like a checkpoint spawning you in the middle of a horde of enemies causing a death loop and forcing you to delete your savefile
i thought it was relatively successful, not to big AAA standards, but made a decent chunk of cash
most of the reviews for it i saw said it was pretty decent for what it is
looked meh to me so i never played it
