Paul writes "I’ve only in recent years become aware of asymmetrical multiplayer as a concept while reading Scott Rogers’ Level Up, a general overview on game design. I think Evolve was the first high profile game that I remember really noticing making use of the concept. Of course, others before it have dabbled with the concept, most notably Left 4 Dead or Aliens vs Predator, but I don’t consider them true asymmetric games, because while giving the competing teams entirely different abilities and mechanics to work with, the teams themselves are more or less numerically balanced"
