Ok guys, for those of you who do NOT have the Online Pass like me, ignore the "Extra Content Required" flag that's attached to this.
You can still play multiplayer, without it. Edit the emblem and profile as such you wish.
For character personalization, reach Level 3 and then go to customize "The Preacher". Then go edit his face, select War Paint 1, and then buy "Primary War Paint 1" for 150 Abstergo Credits. Then back out to the other customizations options and this shall pop!
