Greetings,

I have been doing some digging here and there, and since GOG issues game soundtrack only with names like "Track x", I found a list of names of the tracks.
Please note it might not be 100% accurate, and I also ignored (deleted) tracks which had some in-game voices.

Here is the list (please feel free to contribute).

1. Port
2. Sewers
5. Museum
6. Museum Observator
8. City
9. Laboratory
10. Battle Theme 01 - Player Turn
11. Battle Theme 02 - Player Turn
12. Battle Theme 02 - Enemy Turn
13. Battle Theme 03 - Player Turn
14. Battle Theme 03 - Enemy Turn
15. Battle Theme 01 - Enemy Turn
16. Credits
17. Joan McFadden
18. Mistery 01
19. Mistery 02
20. Orders
21. Game Over
25. Main Theme
