Bethesda doled out several new details on how character progression and abilities function in Fallout 76 during a panel at Quakecon 2018 over the weekend. By nature of it being an online multiplayer survival game, the systems we know from previous Fallout games are changing. Series staples like the SPECIAL system and Perks return, but you'll have to get reacclimatized with them.

SPECIAL encompasses the following stats: Strength, Perception, Endurance, Charisma, Intelligence, Agility, Luck. When players level up, they're given one point to put into any of those stats. The number of points in these stats affords players the ability to equip Perks that are specific to each of the SPECIAL stats.
