Superman: Battle for Metropolis (Jan 12, 2001 prototype)
Discuss this release on our Discord server!
Hello again. This time we have another unreleased game to share with you - Superman: Battle for Metropolis for the Nintendo Game Boy Color!

Developed by Neon Studios and slated to be published by InfoGrames, this game was canceled after failing to impress the license holder for Superman. Regulations that were imposed on the character prohibited the developers from making the game they wanted, and so this prototype was created as a compromise to meet some of the demands of the licensor. The game remained relatively unheard of, as it doesn't seem like the game was ever mentioned in the media or present at any tradeshow at any time during its development. The game was presumably canceled around the time that this specific build was created and possibly never had an opportunity to see the light of day in any form. This prototype was donated to us anonymously and will be the first time this game has ever been seen before.
We hope you enjoy this one and look forward to sharing more goodies tomorrow! Until next time.
