Infinity Music Pack #2 contains 40 game-ready tracks. Each of the four songs comes with the Composers Mix plus 9 Alternative Mixes, often vastly different from the original.

Create Your Own Mixes
Each song is also presented in layers, with a ready-to-use Audio Mixer in the demo scene. Use this to mix your own versions. When you're ready, you can export all mixes to game-ready .wav files with a single click.

Adaptive Audio
Using the Audio Mixer during run-time is easy, as the Mixer can be scripted so that music changes over time, or reacts to in game variables.

The tracks included in this package can also be found in these Character packs, for anyone interested in more than just the music:
