Computer Whiz/Fallout 3

Computer Whiz is a perk in Fallout 3 and Fallout: New Vegas.

Effect
With this perk, you get a second chance for hacking at any computer you were previously locked out of. However, any hacking attempt can be aborted prior to failure, after which the security will reset and it can be hacked again without consequence. In this manner, no computer will ever end up being locked out.

Behind the scenes
