Remember Rachel from the original Nintendo 3DS version of Resident Evil Revelations? She'll be a playable character in the console edition.
Capcom confirmed today that the well equipped Rachel will join the roster, alongside HUNK, in the multiplayer Raid mode feature.

The folk behind Resident Evil also commented more specifically on the Wii U version, which will contain a manner of different control schemes: The GamePad and TV, Wii U Pro Controller or on the GamePad alone via the previously confirmed off-TV feature.

Miiverse also comes into play - more specifically if you're unable to come with the zombie onslaught and end up with a "Game Over" screen. Players can post a message from this screen in particular to others to let them know that the undead have won this round.
In addition there'll be what Capcom are calling the "Creatures Voice" feature, which amusing allows you to add speech bubbles over monsters that appear in-game. "I wuv you, now give me a hug!" would be highly appropriate in this situation.

Will you take on Resident Evil: Revelations on Nintendo Wii U this May?
