You can upload your created boxers/fighters from in the game to the internet. Users can then browse through the uploaded boxers on the website or on their console. They can look at them in a few different ways like most downloaded, top rated and most recent.
If you are browsing the fighter share site while logged into an account linked to the gamertag you can "bookmark" them, which makes them easier to find in the game, though I can't remember specifics.|||i bet it would be like Fight Night Round 4's Boxer Share. you can download other people's created fighters, try the fighter out and rate them. it is up to you if you want to keep the fighter you downloaded on your roster. :)|||Also it only takes seconds to download a fighter
