Rent it for a weekend, it's fun but it gets old in about 10 hours.
The gameplay is basically killing zombies with anything you can grab, with some boss battles, cool weapon combinations, some special attacks and rescuing survivors.
But of course the only fun in rescuing survivors lies in the experience gained from it, who likes escort missions? really.
But here's the thing, as funny as it is to kill zombies in a million different ways, the game is only that, and if it gets old before you complete the story...you will end up enjoying less and less the game, to the point of quitting because it does not hold your attention, which is sad.
But in the worst case scenario, you will get stucked because of the time mechanic, and have to reset the main story all over again.(Yeah, it happened to me.)
This is a major flaw in the game design, because is not even related to how hard the game is, the game penalizes you for having fun without paying attention to the watch, and then it becomes impossible to finish whatever mission in the required time.
And guess what, at least for me, that's what i look for in a game, to have fun and enjoy myself without caring about anything.
So in the end, the game got old , and after the credits rolled, there was a bonus chapter, and I realized that I didn't want to play anymore.I quited, without even caring about how the story ends.
