Question about dead rising.

Ok I have it on Wii but someone said to come here since no one really bought it for that console. I assume this part is the same on all the consoles so here goes: I completed the first mission with an S rank and the 2nd with a B rank. Is there any way to replay them? Also I noticed after I finished one of the chapters (i think thats what theyre called) and I decided to roam around the mall instead of going straight back to the safe room, that lots ofhallways were like blocked off etc, once I get farther into the game they will become unblocked right? and is there anyway to set a waypoint for where you want to go?

I didn't recall Ranks at all in the Xbox version, nor missions, well the kind your talking about, sorry :(.Question about dead rising.
The 360 and Wii version are pretty different, so as stated above, the 360 version is nothing like you said.
It's totally different from the 360 version, you'll have to ask someone in the Wii forum.
