No. There are only preset characters, and like a lot of other multiplayer games as you level up, you'll gain access to new abilities that you can use to customize. Once you level up to a certain point, you'll also unlock new costume variants for each character.
Yoda of Borg are we: Futile is resistance. Assimilate you, we will.
that sounds cool, I was worried there wasnt going to be a level up system in brotherhood, now that I know this, brotherhood turned from a picking it up soon after its released, to a must have on day one. I made the mistake of going into many games when the MP was already going for a while, and getting completely owned, I wont make the same mistake with brotherhood, noobs, prepare to feel that icy blade between your ribs on day one
