Case Zero is a solid prequel that gives you a lot of bang for your buck.
Solid voice acting that is hurt by lack of dialouge, Descent sound effects that grow repetative, and descent music.
Visuals: 7/10
Solid looking character models and environments. I am disapointed that there are little variation in the zombies and the cut scenes dont look as good as they could have been.
Playability: 7/10
Nothing has changed since the first Dead Rising, it is still the same combat and that is very disapointing. The new addition to it is the combination of weapons which add a level of creativeness to the game but that alone cant save it from being average.
Delivery: 8/10
A campaign that gives you about 4 hours of gameplay. The stats carry on into Dead Rising 2, which is a huge plus for anyone who is going to buy the game. Multiple endings add a little bit of replay value to it as well. What I love the most is the fact that the game costs only 400 MS points, That is great considering it gives you hours of zombie killing fun.
Achievements: 8/10
Achievements are fun to get and issue quite a challenge. Makes you explore the entire Dead Rising world before its all said and done.
Overall: 7.5/10
At a great price, Case Zero is a prequel that I welcome with open arms.
