Cryptic Sea's No Quarter is a series of indie games described by the developer as "an album of original games inspired by arcade and console classics. Think of it like an album of music except with games instead of songs."
Part of this 'album' is Hitlers Must Die!, a "run and gun where you play a Soviet special forces guy assigned to kill Hitler clones." Basically, a 2D shooter, with some neat John Woo-style stunts in there, like sliding backwards while shooting. But there's the question: why not just have some cookie-cutter space aliens or monsters? Why Hitler?
But the answer is obvious. Why the fuck not?
Proof that, like Philip Glass, Moonlight Sonata makes any video infinitely cooler.
