The Special Edition Extras for Gunpoint include:

• The Soundtrack: Includes all of the game's noir-inspired spy music in high quality MP3 format.
  
• Developer Commentary: When enabled, you'll find little sprites of Gunpoint's developers on every mission. Talk to us to hear a little about our thinking behind the design (Tom), the art (John), and the music (Ryan).

Caution: shooting a developer while he's talking ends his current commentary track. This kills the developer.
