Biohazard 5: Alternative Edition (aka Resident Evil 5: Alternative Edition) has an extra episode that takes place before the events in Resident Evil 5.
The new area is a flashback where you control Chris Redfield and Jill Valentine in Spencer’s mansion. Alternative Edition, similar to Lost Planet: Colonies Edition, is online compatible with the original Resident Evil 5. However, it isn’t clear if players will be able to use Sony’s motion controller for online play. Also, if you’re not convinvced motion control will make Biohazard 5: Alternative Edition a better game you can play it with a regular Dualshock 3 controller.
