User Rating: 9.5 | Dead Rising X360
In Dead Rising you play as photo journalist Frank West , who looking for a scoop land this and before he knows it is plopped into a mall filled with zombies and having 72 hours (6 hours real time) to survive and find out what happened.
This like many Capcom games is loaded with unlockables and a bunch of other reasons to keep playing like the mega man buster which is unlocked by killing more than 53 thousand zombies!OR the light saber which is unlocked by surviving 14 real hours without saving or starving which is 1 health bar every 90 seconds. Dead Rising also features many costumes by unlocking various achievements.
Also adding to the main storyline are psychopaths the bosses in the game which explain their little sob stories and like 1/2 the time they'll have a survivor who you can lug all the way to the security room for a nice exp bonus.
Anyway you play it dead rising offers tons of hours to have fun and challenge yourself if you haven't tried this game you NEED to try it out!
