A combination of already-existing Mountain Dew flavors:

Code Red

White Out

Voltage

I've tried it and is pretty tasty. 

I am glad they brought it back this year. I loved it in 2017 and hated when Liberty Brew replaced it. I hope they make it the permanent summer flavor.

Got sort of a berry taste.
