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.
