Never played Battlefront, but that sounds like a short duration powerup mode?

I was thinking of something like Evolve[0] where it is a 4v1 kind of humans vs monster affair. There are also horror games that follow this formula -one psycho killer vs regular humans. I assume all the fun is being the monster, less amusing to be the weakling running and hiding.
