Siddharth writes- “The recently released Commander Lilith & The Fight For Sanctuary yep, an expansion for 7 year old game is the final piece in the Borderlands 2 saga and aims to bridge the gap between the second mainline entry and the upcoming Borderlands 3. Its highly recommended that players first finish Tales From The Borderlands as this DLC takes place after the canonical spinoff made by the now-defunct Telltale Games (in collaboration with Gearbox), and as such will have major spoilers for it. Its available to for download free until July 8, 2019 for PC, PS4 & XB1.”
