I see that there are six (6) hidden Steam achievements (Feature Complete, Extra Lives, Nice to Meat You, Teh Internets, Bonus Levels, and Behind the Scenes) with no descriptions and I have no idea how to get them. Do I need to rewatch the movie if I have already? Can I skip around? What are the unlock conditions? Where are they hidden?
According to this site, the achievements are as follows:
Feature Complete - Watch Indie Game: The Movie.
Extra Lives - Watch all the Indie Game: The Movie extras.
Nice to Meat You - Listen to Team Meat's Indie Game: The Movie commentary track.
Teh Internets - Press the Twitter or Facebook buttons on the Indie Game: The Movie extras menu.
Bonus Levels - Watch all the Indie Game: The Movie Special Edition segments.
Behind the Scenes - Listen to the Indie Game: The Movie director's commentary track.
Game Master - Get a perfect score in Indie Game: The Movie: The Game.
