Strength

“ Strength measures your character's muscle power. It affects melee damage and carry capacity. It's also important for characters who intend to use heavier weapons (such as sniper and assault rifles and sledgehammers). ”

— In-game description

Details

Strength determines how much damage you can deal in unarmed combat and with melee weapons. Strength also increases your chance to hit with melee weapons by increasing your melee skill, unless your dexterity is higher. Carry capacity starts at 100, with each point of Strength increasing it by 10. Some other actions (e.g. opening vents with a crowbar) also require a set score of strength. Strength is also a requirement to use heavier types of weapons and armor. You can use heavy equipment without meeting its strength requirements, but too heavy weapons will suffer reduced precision and wearing too heavy armor reduces your action points.

High strength score is important for characters who use the heaviest of armors and heavy weaponry.
