After some time on the Ponynet, Twilight has discovered a new game, Planetside 2, made by Pony Online Entertainment. She gets all her friends to download it, loads up Herdspeak, and when they're all ready to kick tail together, they take separate sides. With both Unicorns on the Luna Sovereignty, both Earth Ponies fighting with the New Conglomareate, and both Pegasi loyal to the Equestrian Republic, they'll have to fight endlessly on the desert of Indar while they discover that Teamwork IS Magic.
