Mourning is the song from Blake Stone: Planet Strike. The song strongly reminds of the Nobody Told Me About id from Doom composed by the same author. It is unknown which of the songs has been composed first, and therefore it is unclear which one is the base and which one is the inspiration remix.
It plays in the following levels (areas) in the game:
- Area 3: Cargo Holding,
- Area 11: Mutant Holding Chambers,
- Area 18: Mutant Isolation Area
