Video: Blizzard's shooter isn't even out, yet some folks have already found ways to play the game absolutely unintended ways. Instead of chasing each other on the map, these players have set up a silly orb deflecting mini-game. It's a reminder of Team Fortress 2 days and Pyro Airblasts. Symmetra is firing her orb to the ninja characters. The first one bounces it off with one of his abilities and you can see them follow a chain until the whole thing loops back. The more orbs are in the field the harder the whole thing gets.
Also it's a custom game mode, so the ninja Genji characters have no cooldown on the deflect ability, and the skater Lucios have a different amount of health.
