I would say I am currently a pro at Pokémon Go (if that is possible), though I used to be phenomenal at Infection in Halo 3 and Reach! When I was a zombie, I knew where the humans would go and how to catch them unawares! If I spawned as a human, I was almost guaranteed a hells janitor at least! I could melee-block swords, wield a pistol with ruthless efficiency, anticipate and counter rushes, and had an escape route for any situation! Good times were had!
