Kindly let me know what the (original) season pass includes, and what it doesn't include. Further, have all of its contents been released, and will future content not fall under it? Thanks.
the Season pass contains all the post-release DLCs coming out in the first year after the game's official release. There are two DLCs as exceptions - the Servo Skull pet and the Charybdis Outpost DLC which were both pre-release bonuses for those who pre-ordered the game.
