Close to Metal

Close to Metal is one of the companion perks in Fallout 4.

Obtaining
To gain the perk, the Sole Survivor has to reach maximum affinity with Nick Valentine, which is possible after completing his personal quest (Long Time Coming).

Effects
The player character has one more guess to dial the password in terminals. Also, terminals have 50% less time to be reset after failed hacking.

Behind the scenes
In computing, "Close To Metal" is an idiom for the lowest level software operations of a computer. It is also the name of a beta version of a low-level programming interface developed by ATI, now the AMD Graphics Product Group.

Bugs

 * The extra guess does not stack with the Science bobblehead.
