Two different duos will be made available: Kane and Lynch from, erm, Kane & Lynch, and Kain and Raziel from Legacy of Kain. Will be "more details soon".
"Which downloadable character pack for LCGOL should come first, Kane & Lynch or Raziel & Kain?" Crystal Dynamics, asking fans to decide. They want you to tweet your answer to them so they can tally the numbers.
"Tons of responses already! Keep them coming guys", they added moments later. Kain and Raziel were last seen back in 2003's Legacy of Kain: Defiance for Xbox and PS2. No release dates or pricing have yet be revealed for the cameo DLC packs.
