Another staggering difference is that Resident Evil: Outbreak is divided into five different scenarios that are pretty independent of each other ' meaning, there's no longer a cohesive story. Your adventure is completely independent from one another, and there's really no pressure to work together. However, just because you're stuck in the same boat doesn't mean you have to work together.
There are still plenty of zombies that are achin' to gnaw at your neck, but now instead of going at it alone, you're working with several other characters - controlled by either the computer or other players if you take it online - to complete the scenarios. Fret not Resident Evil fans, Resident Evil: Outbreak is essentially the same game you know and love minus a few changes.
