Another 2 tracks I found from the Halo 3 Machinima I did a while back. But, anyhow, enjoy them,

Race To The Moon: https://soundcloud.com/nick-rojas-9/race-to-the-moon

Apollo: https://soundcloud.com/nick-rojas-9/apollo

*this one was a pretty bad, imo, b/c the electronic effects. Should've lowered them, tbh. However, if someone asks, the pace of the track may sound like something your would hear from Isao Tomita's Jupiter theme*
