What kind of books, movies, games, shows, music would the Helldivers like?

Random topic, title says it. - Helldivers would probably read books titled "How to stop undemocratic thoughts" or the history of "Lady Liberty". - Shows and movies documenting the First Galactic War about the "Right Side of History". - Games where they play as a night guard fending off automatons on the Super-BOX U (the only, and best console on Super Earth). - And probably listen to heavy metal band called "Flames of Democracy"

In all seriousness I think they'd like playing Metal Slug.
