Spider-Man vs. The Kingpin

Spider-Man vs. The Kingpin is an action-adventure video game developed by Technopop and published by Sega. It was released initially for the Genesis and Master System in 1991 and later ported to the Game Gear in 1992 and Sega CD in 1993.

Plot
The Kingpin frames Spider-Man of a crime of detonating a nuclear bomb in New York City within twenty-four hours. The keys have been dispersed to many of Spider-Man's rogue gallery, including: Doctor Octopus, Sandman, The Lizard, Hobgoblin, Vulture, Mysterio, Electro, and Venom. Eventually, Venom kidnaps Mary Jane Parker. Peter obtains the keys and disarms the bomb and saves Mary Jane before she is dropped into a pit of acid by the Kingpin.

Alternate Endings
Oddly enough, different versions of the game have different endings focusing on the final fight between the Kingpin and Spider-Man.

Sega CD
If Spider-Man beats Kingpin but not in time to save Mary Jane, the police will arrest Kingpin and Spider-Man vows to avenge Mary Jane. If Spider-Man fails to defeat Kingpin, both he and Mary Jane will be tied up and lowered into the acid pit together, both dying.

Mega Drive
Similar to the ending in the Sega CD port, Mary Jane will be killed but Kingpin will escape, leaving a heartbroken Spider-Man on his knees.

Master System
Unlike every other port, Mary Jane is never kidnapped. If Spider-Man fails to defeat Kingpin, he will get away.
