Resident Evil: Outbreak and the sequel File #2 can both be played online with other players once again. Capcom had shutdown the servers long ago, but dedicated fans were able to reverse-engineer custom made servers. The catch is that this will only work with the Japanese version of the game as there are no known packet captures of the American and European versions of Outbreak.
So there you go. If you're a diehard Outbreak fan that owns the Japanese version still, have fun. For everyone else, let us reminisce the part with the zombie zoo animals.
