The game's story takes place during World War II and centers around a cargo pilot named William Augustus Grey (voiced by Nolan North) who is teleported to another world while flying through the Bermuda Triangle. In this world, known as the 'Void', Will encounters an alien race as well as other humans, which are known as the Watchers and the Survivors respectively.
Will reluctantly joins the Survivors who are engaged in a feud with the alien race to satisfy his desire to return to Earth. While aiding the Survivors, Will discovers that the Void is a middle ground that connects both the Watchers homeworld and Earth. It also becomes apparent that the Watchers are supplying the Axis powers with various supplies for reasons unknown. With the help of Nikola Tesla, Will utilizes retrofited Watcher technology to combat the Watchers and eventually find a way to escape the Void.
Like Batman AA, non PhysX testing performance was a little all over the place. PhysX testing on the other hand saw a good boost in performance.
