Attention: Before reading this: My English is not sooooo good

So, ive selected "Rescue the Ark" at first but now i want to be a resistance member i know i can change everytime, but i will join normally as a resistance member in games, and it should be shown as a resistance char in main menu, is it possible?
I wish i pressed "Escape the Ark" I thought Security is cool but the Resistance is cooler

I got the same "issue" (I used the " bicause it's really just a detail). I chosed first the resistance but finaly I prefer my character's Security look, but there is no button to change the default look when navigating into the menus.

Easy solution

Step 1: Create new character
Step 2: Select your preferred faction

Problem solved

And you got a totally new character with level/rank 1 when the other one is level 18. Yeah that's great. In this case I prefer keep my character with the "wrong" look ^^'

You can have both, I have two lv 20 characters one resistance and one security.
This ultimately comes down to you picking the wrong side in the beggining, now either deal with it or create a second character like most people do.

Like I said, it's not a big deal, just a confort matter. If this function is added, that's cool, if not, I'll continue to play and maybe I'll have 5-6 new other characters...
