====== PWR ======
[{{ ui_top_left.png|The agency's PWR reserve is shown in the top left corner of the user interface during missions.}}]

**PWR** (or "power") is a resource required for using most [[:programs:]], and some [[:items:]], [[:weapons:]] and [[:augments:]]. PWR can be gained from [[:programs:#generators|generator programs]], [[:Consoles]], [[:items:Portable Servers]], some [[:augments:]], and by [[:stealing]] from [[:guards:#drones]].

The agency's PWR reserve is shown in the top-left corner of the screen during missions. It is capped at 20 PWR, and cannot be taken below 0 PWR. Unlike [[:credits]], PWR is not preserved across missions; the agency's initial PWR at the start of the mission depends on the [[:mode|game difficulty]]:

  * In [[:modes:Beginner]], [[:modes:Experienced]], [[:modes:Expert]] and [[:modes:Endless]] modes, you start each mission with 10 PWR.
  * In [[:modes:Expert Plus]] and [[:modes:Endless Plus]] modes, you start each mission with 5 PWR.
  * When playing with [[:modes:custom]] difficulty settings, you can set the **mission start PWR** to any number between 0 and 20.

In the [[:missions:Power Relay Station]] side-mission, the agency has the option to sell 15 PWR for 500 [[:credits]].
