Give this game a try, but only for an hour
This game is definitely worth a shot by everyone. I admit I wasn't intrigued at first because it looked like an unoriginal game, but then I started switching the tv channels and tried to earn all of the achievements.
After playing for quite some time, I decided to stop and basically wait for death. The games that I have to do this to always feel like the ending is bittersweet. It could have been more satisfying, although blowing stuff up makes up for a lot of it.
Gameplay not picking up the pace quick enough, not enough of a challenge after about 300,000 points, and not any hint of ever ending (although that is to be expected with a zombie apocalypse) were the only things keeping me from fully enjoying the game. I really enjoyed the tv concept, the gunmen during the actual game, and the overall good quality of animations.
