Just thought I should remind you to check the Catyph film OST ! It released in January 22nd 2014 and is a good preview of what you can expect in the game. Some tracks like Mind the Mines are just incredible and The8thStep did an excellent job for Karreo.
If you like the Catyph soundtrack, you could also get deeper in the ASA OST. The 2 games and worlds are linked, and the music too. Please consider buying it if you wish to support Stélian and Karreo, so they can do an amazing job on Catyph:TKE.
