Spineless

 is a perk in the Fallout: New Vegas add-on Old World Blues.

In the initial dialogue with Doctor Klein as part of the Welcome to the Big Empty quest, you find out that your brain, heart, and spine have been removed and replaced. This perk represents the replacement of your spine. While you technically have these perks from the start of the DLC, they are unlocked in the course of the conversation.

The description of the perk reads: "Your spine has been replaced with advanced technologies: Your torso can no longer be crippled and your Strength (STR) and Damage Threshold (DT) have been increased (+1).

Effects
This perk removes the ability for your Torso to be crippled, and adds a bonus to Strength and Damage Threshold.
