Ain't Like That Now

 is a perk in the Fallout: New Vegas add-on Lonesome Road.

Effects
Maybe you were bad once, but you ain't like that now. Your Karma has been reset to 0, you regenerate AP 25% faster, and your attack speed is increased by 20%. You are also immune to critical hits.

Behind the scenes
The name of this perk may be a reference to the Clint Eastwood film Unforgiven, in which the character William Munny declares he "ain't like that now" whenever his past acts of gunslinging and murder are discussed.
