Ever since Activision released their Nazi Zombies game mode in Call of Duty World at War, I have been a huge fan of the "Zombies" franchise.  I think the co-op survival game is incredibly entertaining; the fact that you can never officially win only increases replay value by trying to beat your best round score.

I wanted to create a portfolio piece that is reflective of my current skill set, and opted to do a Unity version of one of my all time favorite game modes.
