It looks like Far Cry 4 is getting a DLC season pass, if a listing on GameStop is any indication. Though Ubisoft has yet to formally announce it, it wouldn't really come as a surprise given the publisher's recently revealed plans to increase sales of digital items for games.
GameStop currently lists the Far Cry 4 season pass for Xbox 360, Xbox One, PS3, and PS4 for $30. Unfortunately, it offers no details for what the season pass will entail. 2012's Far Cry 3 didn't have a season pass, but did see four expansion packs released for it, all of which were eventually bundled into the Far Cry 3: Deluxe Bundle.
Far Cry 4 was revealed last week, with the game's story oultine spoiled by a listing on Ubisoft's Uplay store. Ubisoft will offer a more extensive first look at the game during its E3 media briefing in June.
