Whip? Combat Cross? Nah, Dracula uses a sword. The Castlevania: Lords of Shadow 2 trailer shows Gabriel Belmont using a blade. Konami confirmed this is a new weapon called the Void Sword. (Update: I should probably clarify that this isn’t his only weapon, Gabriel has a whip too!)
Castlevania: Lords of Shadow 2 takes place centuries after Lords of Shadow where a withered Dracula wakes up in his castle.
Konami has Castlevania: Lords of Shadow 2 scheduled to come out in 2013 for PlayStation 3, Xbox 360, and PC.
