Snowy Mountain has you go into the mountains and fight what else, but dogs. Dogs have always been a staple for the Resident Evil franchise, and here they are again living in the mountain. I recommend bringing a shotgun along on this mission, as well as some B.O.W. decoy grenades.
In this video, I go over some of the basics in the game mode and how it works, and then we go over some basic gameplay.
Resident Evil Revelations released on May 22, 2013 for the Wii U, Xbox 360, Playstation 3, and the PC. This version is a HD port of the 3DS exclusive, and the Raid mode is a new addition to the game. I am playing the Wii U version.
