Legion Assault/Fallout: New Vegas

Legion Assault is an unarmed perk in Fallout: New Vegas.

Effects
After talking to Lucius in Caesar's Tent with an Unarmed skill of 50 and a good reputation, he will teach you how Caesar's elite cadre of bodyguards, the legendary praetorians, use an aggressive Legion Assault to brutalize enemies.

Perform a power attack while running forward to perform the Legion Assault. When performing this move in third person, the Courier runs forward, leaps into the air, and thrusts their right palm forward before landing back on the ground.
