Aside from customizing Faith and changing her into the Runner you want her to be via Runner Echoes and abilities, you can also change up the way you're represented in-game by way of your Runner Emblem in Mirror's Edge Catalyst.
Unfortunately, this is one aspect of the game you'll have to actually change online via your EA account rather than in-game. If you're playing on a console you'll have to get on a computer or your phone to tackle this part, which is a bit jarring considering you can make all the other alterations you need in-game.
To kick things off, head to MirrorsEdge.com, as you'll see in the screens so graciously provided by Josh (Thanks Josh!). Log in with your EA account and you'll be greeted with a screen where you can select different emblems, frames, and backgrounds to create a special Emblem that you'll be represented by in-game going forward.
Click on your profile in the top right corner of the page and click "View Profile" to be taken to the tools to edit. Here, you can also view the map, others' challenges, and issue challenges to other people so they can come back to them easily.
As you progress through the game you'll unlock Emblems as you will Runner Echoes, You'll find all of your collected Emblems here, so any time you get a wild hair and want to change things up a bit, be sure to log in to check and see what you've collected as well as what image you want to use to represent yourself in the online world of Mirror's Edge Catalyst.
That's about all she wrote for this how-to, but it's not that difficult to start with. It's a little time-consuming if you don't immediately want to hit up a computer or the app, but very easy to do and helpful since the game isn't always forthcoming with the information you need to put it together yourself.
