finished the Lake House DLC for Alan Wake 2, it was great. Had some little hints to Control 2 that I don't entirely know what to make of yet but I am foaming at the mouth waiting for that now.
doesn't need anything else, you boot it up separately from the main menu. Took me like...probably 3 or 4 hours, tops? Fairly short but good (though I was using the gameplay assists because I am out of practice with the game and some of the combat encounters were tough and I was mostly playing for the story/lore)
