Melee Hacker

Melee Hacker is a challenge perk

Requirements
The requirements for this perk aren't entirely straightforward. First one has to complete Up Close (50 melee kills), which will unlock Up Closer (75 melee kills) which one will also have to complete. Completing Up Closer will unlock I Can Do It One Handed (10,000 damage with one-handed melee weapons) and Two Hands are Better than One (10,000 damage with two-handed melee weapons). Those two challenges will reward you with one rank each.

Effects

 * Rank 1: +5% Melee attack speed
 * Rank 2: +10% Melee attack speed
