Machine Gun Arrow, called Left Chain Fists (左連拳 Sarenken) in Japan, is a move used by Forest and Marshall Law, as well as Lee Chaolan prior to Tekken 4.

The move is performed simply by pressing 1,1,1,1,1 and consists of a series of fast high punches. The move can be extended by chaining into another attack, the Rave War Combo, by pressing b2,2,2 after the fourth hit.

If the first hit connects, the speed at which the following hits land make it difficult for the opponent to break or counter the move, making it a good move for quickly draining an opponents health; however, the short range and single height of the punches make it a risky and easily countered move at high level play.
