Notes
- The game is loosely based on the Infinity Gauntlet storyline.
- Thor's design is based on Eric Masterson's Thor costume[1], which is a reference to Masterson being the Thor involved in the Infinity Gauntlet storyline. Captain America's ending in the game however, shows that this is Thor himself rather than Masterson, as he spoke with Odinson's manner of speech and Captain America referred to him as Asgardian.
Trivia
- This game was dedicated to the memory of Jack Kirby, with character artwork based on his old designs.
