Dino D-Day is a multiplayer team-based first-person shooter video game developed and published by American studios 800 North and Digital Ranch. It was released for Microsoft Windows on April 8, 2011. The premise of the game is that during World War II, Adolf Hitler found a way to resurrect dinosaurs for use in the war effort. Players can battle online choosing to serve either the Allied nations or Nazis. The game was described as a new twist on "the overdone World War II FPS [...] that has become a running joke in the industry and gaming press".
