(see below for clue...)
I was testing out the desert pack with v1.007 beta of The Game Creators FPSC Reloaded game engine and getting into the old "New Mexico" frame of mind, when a piece of incidental music from a film popped into my head.
So, I decided to write it up in CakeWalk Sonar X2 and stick it into the level.
Can anyone guess the film?
Clue: This film maker usually writes all of his own music for his films (his flicks are usually of the scary kind)!
