Wired Reflexes

Wired Reflexes is a Fallout 3 perk. It cannot be taken on level-up, but is available through The Replicated Man quest.
 * Requirement: Side with Dr. Zimmer in the quest The Replicated Man (betray/report A3-21). The PC is NOT required to "truly" betray A3-21, as killing Zimmerman directly after receiving the perk from him will result in A3-21 being saved (and positive Karma). This path allows the PC to achieve both quest rewards (the other being A3-21's Plasma Rifle) instead of only one reward. This path also results in no net Karma change (-200 + 200 = 0 Karma).
 * Benefit: Advanced technology from the Commonwealth which increases your reaction speed, giving you a higher chance to hit in V.A.T.S. by 10%.
 * NOTE: This is an estimate, in reality, just like crouching, the bonus scales from one weapon to the next, expect to see a higher gain with a sniper rifle, for instance.
