“A "Big Frigger" power fist from BeatCo. Considered by many to be the ultimate weapon to use in unarmed combat. Others are just scared. Powered by small energy cells.”
A mechanical armored glove powered by small energy cells. It likely works similarly to a super sledge, using a kinetic energy storage device to amplify the wearer's punches by unleashing concentrated energy through armored studs on the knuckles, while keeping the wearer's hand protected from damage. Unlike a super sledge, it cannot knock targets back. It is the most expensive unarmed weapon in Fallout. An improved version of this weapon exists in Fallout 2.
The power fist was a late addition to Fallout. Balancing for various forms of combat went on until very late in the game, when it became clear that characters specializing in unarmed combat couldn't keep up with the damage output necessary to finish certain battles near the climax; even when scoring critical hits, unarmed attacks rarely penetrated armor or did enough damage to keep the Vault Dweller competitive. Various "unarmed" weapons were added as a result, but initially only the brass knuckles and spiked knuckles were included. The power fist was included as a final upgrade, a natural addition to power armor, and a thematic tie-in to the power-assisted hand-to-hand combat portrayed in some dystopian futures of science fiction, such as Warhammer 40,000.[1]
