I was browsing the web when I decided to see if anybody had made Ezio Auditore and lo and behold, they had! All I could find was this video, but there's a download link in the description. Tested it, no viruses. He's a four-button character, handles well. Has one kinda strange crouching kick.
I'm new here, haven't played mugen in a while, but I thought I'd make an account here just to let people know about this character. Might start up my collection again, definitely adding him. Cheers
