Overall, Dead Rising: Chop Till You Drop is a worthy port. The story is still intact, the weapons and guns are easier to use, the number of zombies is still perfectly fine, and there are some unlockables and extra modes to keep you playing. Unfortunately, some of the changes are for the worse. The graphics, of course, have been turned down, sections have been roped off, the camera is gone, the number of weapons have decreased, and the missions are set up in such a way that brings about a feeling of repetition and a loss of freedom.
If you have the 360 version, then there is absolutely no reason to get Chop Till You Drop, however, if you haven't played the original and like destroying zombies, then you'll probably enjoy the game.
