Most of the gamemodes right now, focus on standing still and shooting a target that is in-front of you. But that dosn't really simulate a real game.
That is what the new gamemode focus on, your goal is to get through the map as fast as possible while shooting all the targets. So a lot of running and shooting, and bigger flicks.
The current version of it is more of a test, it's gonna get larger changes in the future, and the possible to make your own maps, with workshop support.

Patch notes
Build 128: Introducing Skeet Shooting: Corridor
In this new room you are in straight corridor, and shooting targets when they popup around the corner. This is just the first of many skeet shooting based rooms.
And yes I know this isn't really skeet shooting.
