Nazi Hunter is a solo or 2 player cooperative game in which you are tracking down and arresting Nazis who fled to Argentina after WWII. It is currently only available via the Nice Games website.
The game involves some character creation, as you design your team of two hunters. This part is crucial to winning, as you have to find the right combination of abilities for your characters that will make them work well together. From then on, you use the main board to see if you can catch the fleeing Nazis. If the enemies escape via plane, train or ship, you lose. Your goal is to arrest as many Nazis as possible and lead them to the court of justice.
The company recommends this as a game to play on an airplane tray thanks to its small size and portability. As those Nazis that you let escape would do.
