Crippled Leg

Crippled Leg is a condition in Fallout, Fallout 2, Fallout 3, Fallout 4, Fallout: New Vegas and Fallout Tactics.

Fallout 3 and Fallout: New Vegas

 * Slows down the character, proportionately to being over-encumbered.
 * If both are crippled, it slows down the character further. It also gives them a limp when walking in third person.
 * If both legs on the player character are crippled, they can no longer perform special moves like Ranger Takedown or Khan Trick.

Fallout 4

 * Prevents from running and slows down the walking pace.
 * When both the player's legs are crippled, traveling in third person is drastically slower than traveling in first person.
