Press White, Black, L, R, X, B, Y at the main menu. Start a new game to begin with the Soul Reaver and Iron Armor.
Use Iron Armor from Blood Omen: Legacy of Kain and The Soul Reaver
At the title screen enter (white button, black button, left trigger, right trigger, X,B,Y) and start a new game. You will start the game wearing the Iron Armor and weilding the Soul Reaver. Note: There is a graphical glitch in some cut scenes. The Reaver is embeded in Kains shoulder. Its actually rather funny looking.
