Borderlands: The Pre-Sequel might feel like an expansion already for the Borderlands series, but the game still entails DLC of its own, as well as a Season Pass. Said pass will cover four post-launch content packs, excluding the pre-order bonus Shock Drop Slaughter Pit.
Gearbox and 2K have promised no less than four DLC packs, which will "encompass new characters, missions, and experiences" after Borderlands: The Pre-Sequel is released in October. Individually, the add-ons will go for $9.99, totalling $39.96 without the Season Pass. If you do get it, however, then those four undisclosed packs will be $10 cheaper, at $29.99.
Publisher 2K Games also saw fit to specify that because The Pre-Sequel is about finished, the developers are able to focus on the DLC. The pre-order DLC, Shock Drop Slaughter Pit, will be released "at a later date" as well.
Borderlands: The Pre-Sequel is expected to arrive October 14 for Xbox 360, PlayStation 3 and PC.
