Sky Sharks was a Kickstarter movie from late 2016 that has finished filming and is heading into post-production.
Essentially the premise is:
Sky Sharks - Deep in the ice of the antarctic, a team of geologists uncover an old nazi laboratory still intact where dark experiments had occured. In order to conquer the world, the Nazis created modified sharks who were able to fly and whose riders are genetically mutated, undead super-humans.
Which I feel could work well as a NachtWölfe experiment in the Antarctica Base and could be an interesting side Trek for “Assault on the Mountains of Madness” if the player’s were to get lost of sidetracked.
