There have been some streamers playing him, how? Not sure.
HAND CANNON
Doomfist fires a short-range burst from the knuckles of his fist. Its ammunition is automatically regenerated over a short time
SEISMIC SLAM
Doomfist leaps forward and smashes into the ground, knocking nearby enemies toward him
RISING UPPERCUT
Doomfist uppercuts enemies in front of him into the air.
ROCKET PUNCH
After charging up, Doomfist lunges forward and knocks an enemy back, dealing additional damage if they impact a wall.
THE BEST DEFENSE...
Doomfist generates temporary personal shields when he deals ability damage
METEOR STRIKE
Doomfist leaps into the sky, then crashes to the ground, dealing significant damage.
Seems he's a melee hero.
