Brink’s “story” is told by actually winning matches as the side whose story you wish to see by having the missions come at you kinda like a push map, where whoever won the previous map advanced forward for their side, pushing the other side back. It actually kinda sucked if you wanted to know the story (not that it had a good one anyway) since there was a good chance you’d never actually win the last few maps since they were harder for the attacking team than the defenders.

From your description it sounds similar but on a bigger scale (and not PvP). I’ve still got a couple days before I can buy it.
