Tonally this is probably one of the more unique entries I've come across. Red Lenses really does capture that infiltration vibe. Laden with tension throughout, swelling as the situation grows more and more uncertain. I love the choice of voicings in this track - it feels so diverse but packages together really nicely.
Pale Fire is much of the same - this actually gives me MGS1 vibes. The short plucky synths, use of semi-open and open hihats and tom hits, and the low piano drone notes really sell this for me. Not often I get that kind of a vibe from music as I feel as though that style was very unique to MGS1 itself. Great work!
En Force has some really nice acid-sounding bass offsetting the typical bass. Guitar work here is pretty solid - sets the tone and gives some much needed bite to back up the title of the track. The choice of chords and guitar textures in this one reminds me of both Tekken 3 and 4!
Ending with Finally Free - this track does the title justice. Large departure from expectations when it comes to choice of instruments and voicings. It feels rather pensive and does good work of cleansing the palette to end off on.
All in all, great work! These tracks really reminded me of some older games that I now need to go back and play again.
