Resident Evil Revelations is an original look inside the RE world taking place between RE4 and RE5. Revelations allows you to experience the events after the counter-terrorism group called the Bioterrorism Security Assessment Alliance or BSAA for short, was joined by new team members Chris Redfield and Jill Valentine.
The trailer gives you a few shots of Chris and Jill in various places including a huge ship and another mansion. RER promises to return the game to its survival horror and puzzle solving roots. The game will use the MT Framework engine used in RE5 and will be released for the Nintendo 3DS.
