6.5 - Presentation
A good story mixes with a helpful map, statistics menu, and side quest selector. The frustratingly limited save system and frequent load times bog down this score.
8.5 - Graphics
Tons of zombies onscreen, very rare framerate hitches, plenty of visual variety, lively animations, and a very well detailed mall.
9.0 - Sound
Squashing a skull has never sounded so good. Dead Rising is infested with excellent audio. Voice acting is pretty good, and the music is hilariously appropriate.
7.5 - Gameplay
There's lots of killing to be done, and plenty of ways to do it. Controls are overall adequate but cumbersome when precise timing is required, and the NPC A.I. can get in the way.
8.0 - Lasting Appeal
Though it'll be familiar ground after a while, the sheer amount of things to do will keep you coming back. The three game modes provide different experiences. Where's the multiplayer?
OVERALL:
8.3 - Impressive
