Yeah, i saw that wiki entry but wasn't sure if it applies to FO1 or is an addition to FO2. Thanks.
The attack moves are Fo2 only.
Unarmed isn't an easy type to use in FO1 due to the limited damage opportunities. To increase damage, you either need an "unarmed" weapon (like the Brass/Spiked Knuckles and the power fist), increase your strength, take a relevant perk/trait, or aim at a body part (as this increases your critical chance)
