The Hum: Abductions

Well there is a game called "The Hum: Abductions" that is an alien invasion simulator.

Per the website:
"For years, people have been hearing mysterious, foreboding, mechanical type noises around the Earth without explanation. The source could never be identified. It was blamed on machinery, electronics and even the Earth’s moving tectonic plates, but not a single scientific mind could locate the cause of this strange phenomenon.

One day the source of The Hum was revealed, and all the conspiratists were wrong.
The Hum: Abductions

The Hum: Abductions is a first person horror game, under development using the powerful and visually appealing Unreal Engine 4 engine.

Thought of as an immersive and frightening story driven game, Abductions is a prequel for The Hum Game, The Alien Invasion Simulator, both parts of a huge sci-fi / horror universe called The Hum Universe.
Story

In “Abductions”, you will play the role of Holly Sanders, a mother and wife, who is living hard days since her husband’s mysterious vanishing, months ago.Lonely and disturbed, with her little son Dan as only company, Holly will uncover the past and present events of the Sanders family, while facing a terrifying approaching revelation"

Now, The Hum (audio sample), is an actual phenomena that people are experiencing but is not necessarily related to alien abduction. This noise is heard of all over the world. In North America it is blamed on Project HAARP and AURORA. During some abductions, there is a precursor of odd frequencies that abductees hear, the hum is one of my different sounds. This one is similar, but is usually because of the EMF disturbance an alien technology causes in the area, which I have heard myself.
