ABOUT THIS GAME
At the beginning of the Resident Evil Revelations 2 story, fans expect the dramatic return of their beloved heroine Claire Redfield. Having survived the Raccoon City incident described in previous Resident Evil games, Claire now works for Terra Save, which fights against bioterrorism. During a party to celebrate Claire’s recruitment at Terra Save, unidentified armed groups burst into the company’s office. Forwards stun Claire and Moira Burton, who was also present at the party. Subsequently, both of them regain consciousness in a dark and abandoned prison. Together, they must find out who abducted them and for what sinister purpose. Will Claire and Moira be able to escape and find out why they were brought to this distant island? The plot, replete with unpredictable twists and turns, will make players rack their brains at every turn.

Heading to a distant prison island in search of his missing daughter, Barry Burton meets a completely new character - a little girl named Natalya Korda. She has unusual abilities that allow her to sense enemies and hidden objects. Using these skills along with Barry´s proven fighting skills, players will need to switch between two characters in order to survive on a mysterious island and find Moira. Barry must spend ammunition and weapons wisely, as is the case in the classic survival horror - after all, terrifying enemies are waiting for him around every corner.

The story told in Resident Evil Revelations 2 continues the episode of the original Resident Evil Revelations. Initially, RER 2 will be released every week as separate episodes for download starting February 24, 2015. Players will also be able to purchase the full season or boxed version. This way, fans will receive each episode as they appear, along with additional content. Each episode in Resident Evil Revelations 2 includes Raid mode content, as well as two fully play-ready scripts that focus on the previously announced characters Claire and Moira and the recently confirmed storyline of Barry and Natalia.
