Geez, these Amiga composers killed it on almost every game with "Alien" in the title. This is a fantastic album. It's short but those first three tracks are great. Ending/Unknown 1 (they're practically the same) contain two loops- one slower and one faster. The first loop cuts off rather abruptly, but it's awesome, even if it is only ten seconds long, while the second loop still being quite good. Overall, 8.87/10 for this.
Just listen to the first three tracks. They're all winners.
