This content requires the base game Heat Signature on Steam in order to play.

## About This Content
This pack contains all the extras you get with the Supporter’s Edition of Heat
Signature, so you can buy it to upgrade to that edition.
* Play through Heat Signature’s development with 8 early prototypes from its 3.5 year development.
* Watch 9 developer commentary videos showing and explaining its evolution: from drilling through hulls to liberating empires. (Total: 70 minutes)
* Own the full soundtrack in 320kbps MP3 format. (19 tracks, 83 minutes)

On launching Heat Signature, you’ll have a new option to open the folder
containing all these extras.

Please note: the early prototypes are by definition unfinished versions of the
game, so they have bugs.
