Normally miniguns just sound like regular guns. With this mod, they can sound like Top Gun(s). Yes, I went there, and I'm not sorry. Not even a little bit.
The mod, created by Pynkie, gives the Heavy's minigun the ability to spew chunky '80s riffs alongside hot lead. If you merely rev it up but don't fire, you get the iconic opening riff from Kenny Loggins' "Danger Zone." The second bullets start flying, however, Loggins' vocals soar high into the sonisphere, like something other than a plane because that would be too obvious.
It is goofy. It is great.
So hurrah for guns making noises they're not supposed to make. Now then, who wants to replace every Scout footstep sound with Taylor Swift's "Shake It Off" for me?
