Case Zero occurs 2 years before the events in dead rising two it gives both story and a sample of the game itself.
AND
the main reason I wanted to make a thread about DR:Case Zero, my Summery of the 5 Results A-F endings
V Seriously Spoilers (not just use of the spoiler tags) V
Ending F- Given when you do not give Katie her medicine in time- Game Failed (no resulting cut-scene EDIT: i heard that there can be a scene for Ending F, I may have missed it or it may have a certain trigger)
Ending D- Given when you do not complete the bike before the military arrives- Cut scene of Chucks daughter being taken away while chuck is held down and punched out
Ending C- Given when the bike is complete but you do not attempt to escape on it - Same Cut scene as ending D
Ending B- Given when you are on the motorcycle but do not escape before the time limit expires- Same Cut scene as ending D and C
Ending A- Given when you successfully escape on the motorcycle. - Cuts scene of Chuck and Katie driving away then finding his stolen truck on the side of the road. The Theif is dead in the front seat. Chuck retrieves his Jacket, Zombrax and Katie's backpack and then proceeds on the motorcycle down the road.
Personally I was kind of hoping for a bit more diversity in the endings, but i guess that maybe asking a bit much.
