You will have your hands full of features with this major update!
The "Golden Scarab" (1.4) update features Gil's Secret Library (if you have the DLC). Gil's Library introduces a tremendous amount of lore behind the game.
Plus we have included Captions/Subtitles. Captions are helpful for the tapes and dialog elsewhere in the game.
And last, but not least, we have built-in a treasure cache of Steam Achievements for you to collect on your journey!
