It was revealed during a during a Nintendo retailer briefing by Resident Evil: Revelations producer Masachika Kawata, that players will be able to unlock the game’s online co-op, Raid Mode, only after completing the main campaign. It was also announced that after the core campaign was finished, Jessica and Obrian will be unlockable as well. It has been noted previously, the main playthrough will last around the 10-hour mark, so be prepared to set aside an allotment of time in order to participate in the co-op. Revelations is set for release on 3DS in February. Thanks: Andriasang, Shack.
