This is what happens when you swap the character models in Lara Croft and the Guardian of Light for Raziel and Kain from the Legacy of Kain series. It's ... weird. Just weird. The bizarreness only increases when you see these characters in motion, complete with unchanged voices.
Watch at your own risk. The downloadable title will be getting a Kane and Lynch character pack sometime down the line as well. Developer Crystal Dynamics is asking fans to tweet which duo they think should be released first. Clearly, there is only one answer. (Raziel and Kain. Duh.)
And I have to ask -- why is Kain so ridiculously happy? There's a reason why he normally doesn't smile.
