For instance, Alien vs. Predator released in 1994 and featured up to three players in one of the era's best arcade brawlers. Capcom developed it according to a film adaptation of the comic book series that was in the works and supposed to release around the same time as the game.
Of course, in reality Alien vs. Predator the movie didn't come out until a decade later, but that didn't stop the gorgeous 16-bit beat ;em up from being a super satisfying cabinet to dump spare change into.
Jumanji: Welcome to the Jungle has the added benefit of technically being about people trapped within an actual video game, but sadly the economics of licence movie games and arcade machines being what they are, Castpixel's art is the closest we'll ever get to a retro adaptation.
