Where horror and shooters meet

Graves's previous work includes the soundtrack for Dead Space 2, while Riepl composed the score for Gears of War. Both of those games influenced their work on Resistance: Burning Skies.

"Dead Space needs to have that atmosphere and that tension to kind of build up before something attacks you," Graves said. "I know everyone considers Dead Space sci-fi, and it is, but it's more horror than it is sci-fi to me, especially with the music."

Burning Skies, on the other hand, is more of a "good old-fashioned adventure score almost that just happens to have aliens in it [laughing]."

And Riepl learned a lot from weaving themes in and out of the Gears soundtrack. "We tried to keep that in mind as we were writing," he said.
