Unsung Heroes was an action / adventure game that was in development at SCEA San Diego from 2002 to 2004 (formerly responsible for Mark of Kri), but the project was later cancelled when half of the team was laid off. There are almost no informations about the game, but from the few screenshots that remain, we can speculate that it was going to be some kind of super-hero game set in a sandbox world.
In 2007, developers of Sony San Diego tried to resurrect the project. Though this was all but successful, you may take a look at the video presenting a PS3 demo of the game.
I'm an Italian gamer with not enough free time to play as much as i'd like to and sadly not enough time to write about cancelled and beta games. Founder of Unseen64 in 2001, i'd like to sleep more than 5 hours a day, but i have to pay the bills. I'm currently working for various italian & international websites for a better User Experience & Search Engine Optimization, you can add me on Twitter, Last FM or contact me by email.
