National Videogame Museum:

We recently unearthed these conceptual promotional pieces for an Alien vs Predator game for the Sega Genesis that never saw the light of day.

…But this wasn’t just any Alien vs Predator game, this game was an ALIEN VS PREDATOR FOOTBALL GAME!

The game appeared to be called “Cosmic Hard Bowl" and featured the Aliens and Predators settling their long conflict through…American Football. No, we can’t believe it either.

Absolute lunacy.

There are all sorts of details and scans over on the linked page (translated from Japanese), but to answer one key part - this wasn’t a football game with just two teams, Aliens and Predators basically split up into the AFC and the NFC, each with unique city-based teams.

Goddamn I hope there’s a ROM.
