Looks like GameStop jumped the gun, outing a Season Pass for Watch Dogs.
It’s not a bad thing though, as it looks like the season pass unlocks some DLC. IGN spotted the listing for $19.99 which gifts a new playable character and mini-campaign of missions, much like Assassin’s Creed IV: Black Flag’s Freedom Cry DLC.
The season pass will save buyers 30% of the cost had players bought the individual bits of content separately.
