First-person '90s 'em up, Gone Home, receives a free update on the 22nd of this month, in the year 2013. That's today! Fullbright's tallest developer, Steve Gaynor, explains: "All of the developers on the game, as well as Sarah Grayson (the voice of Sam), Chris Remo our composer, and (in a super weird & cool twist, to me) Corin Tucker from the bands Heavens to Betsy and Sleater Kinney, recorded audio commentary." This is a free update, and it'll work as it does in other first-person games, with triggers around the game where you can hear folks talk about some game-relevant.
Gone Home has proven rather popular, shifting over 50k copies, and making Alec do a biographical skit.
