if you are a pokemon fan who likes collecting the games

have you ever heard of the game "Mewtwo strikes back 2"? I'm not talking about the second Mewtwo movie, i heard about a game called Mewtwo strikes back 2. my friend said it was the one pokemon game with blood. i asked my other friend about it(they haven't even met each other) and he's heard of it too. he said it's hard to get, like you have to download it then extract it onto a game disk for Xbox or something. i won't ever, unless presented with a TON of logic, believe it's fake.
