Nightmare mode is a more advanced difficulty level in the resident evil series. nightmare mode was first used in the dreamcast and windows ports of resident evil 2. in the playstation 2 exclusive title, resident evil outbreak file#2, it is also featured where it can be purchased for 1000 points.... Resident evil outbreak: file #2, months after, nightmare mode, infinite mode, and changes to the area system were made. hdd support was dropped from the area screen, but players could still host games with hdd mode turned on by activating it offline..
