I'm pretty sure that at least one wolfer noticed this (i think we can call it) easter egg before, but i just discovered it recently.
While playing level 1 of Spear: Resurrection, you can hear a track that is almost identical to the theme of the '76 movie Assaulth on Precinct 13. (directed by the one and only John Carpenter)
You can listen to it here: https://www.youtube.com/watch?v=PoplzqcUa8Q
Since the theme itself is a cool piece from Carpenter, i consider this a pretty good easter egg
