Zombies are the newest threat in Rainbow Six: Raven Shield! Based on the popular Zombies mode from Call of Duty, the team has created a multiplayer and singleplayer mod for Raven Shield which is based on survival against waves of zombies. Each wave gets faster and more difficult!
This is the zombie mod running in Xanatos's excellent Nuketown remake for Rvs. I'm hoping to get Xanatos's permission to include this map as part of the zombie mod.
