So I've played Brink all the way and some of the things said at the end of the Canon story and what-if missions got me thinking

If Brink had a sequel with a fully out story what would it be like?

Personally i think the game would play out Left 4 Dead style with class based combat and Free running,where the "Old Worlders" Attacked the ARK and Security had to fight to survive..

or The Resistance got to the Old World and fought to make a home maybe return to get there families and have to work with Security etc.
