As part of the pre-production of a video game, I was asked to do research on a post-apocalyptic sound environment.

Here is the spitch:
In the near future, our planet is the target of an alien invasion, impressive UFO fly over cities, destroying everything around them. We are in an old apartment, the fron wall ripped open that offers a panoramic view of a devastated city:

Shooting UFO is split into three phases:
–> Loading –> Pre-shot –> Shot

This Pre-shot have two functions, it warns of imminent shooting and brings personality to these machines. The design of this sound is similar to granular synthesis, I cut small samples and duplicated it several times.
The length gives the height and reverb brings the “weight” and depth.
