Generic sci-fi drone. Created on a keyboard. Could be the sound of an alien vaporizing someone with some kind of ray/mind device. Or the sound of strange chemicals combining. Possibly a sudden super-dramatic character movement/drug freakout.
A sound of a sci-fi sniper rifle and reload. Made in ableton 10 with the help of xfer serum and a bunch of processed and resampled oneshots (which were also made either in serum, or granulator, or some other processing tools).
