Surviving the zombie apocalypse is easier with a team. On your next mission, click "Group Characters" below your avatar and you'll be better equipped to keep your team safe and together. You can always "Ungroup" your character if you need to split up for individual objectives like distracting a walker or to conserve energy. But sometimes it's best to take Rick's advice and "stay in tight formation." Give this technique a try in The Walking Dead Social Game the next time you play.
