S.T.A.L.K.E.R.: Clear Sky - Combat Themes [redo]

Ended up redoing the arrangements of the Combat Themes from Clear Sky, after not being too happy with my first versions. Combat Theme 2 is the same as my last one, I just took it down so I could have all 3 in one video.
0:00 - Theme 1
2:31 - Theme 2
5:39 - Theme 3
