New to Tekken 7 and replacing bound from previous entries is the screw system
Screws are primarily used for extending air juggle duration and wall travel.
Each character's screw attacks are noted in the in-game movelists with a green icon. This indicates that if that move lands on an airborne opponent, they will be put in screw state: spinning in the air before landing on their shoulders, feet in the air; allowing for reliable follow up attacks to continue the air juggle.
