For a game that lacks multiplayer, it still has a lot of replay value along with a lot of non-stop action.
In Dead Rising, in order for you to get your story, you must complete several cases, all in witch occur at different times. As you go through the game the first time, trying to level up and completing cases, you will have to travel through huge number of zombies with a wide variety of different weapons, witch basically means the entire game can be a challenge. Once you beat the game the first time, you can go through it again and try and complete every scoop, witch are basically side missions that involve saving other people. Though it seems highly boring, just killing zombies all day can actually be very amusing with the number of weapons and skills you can use on them, with the addition of changing your clothes witch can be very amusing, especially when you can even change into girls dresses or kids shorts. If less you like not being able to see, the game doesnt seem to be too much fun anymore when the mall gets dark usually at night because pretty much everything seems to be pitch black.
There is no online gameplay but however there is a ranking system, on how long you have survived in infinity mode, on xbox live. Infinity mode is unlocked once you have finished overtime mode, witch is unlocked by finishing 72 hour mode. Infinity mode is an extra challenge where you can see how long you can survive as your health drops down slowly and the only way to get it back up is eating and drinking all sorts of food.
Dead Rising is a must have to all 360 owners and a very addictive game if aimlessly killing zombies is your type of thing.
