Like a world of robots or something. I thought it would be neat if there was a game like, say, Chrono Trigger, but everybody's a robot. If I ever make a game like that it would sound like this.
Fl studio has a few project templates. There's one called "Rock" that has a nice drumkit included, so I went with that. I also used Tweakbench's Peach for lo-fi sounds. I was lazy and let the built-in compressor/limiter mix the track for me.
