In Wolfenstein: TNWO chapter one, and i'm trying to unlock the tactical perks. they require 15 behind cover kills with the pistol and 80 behind cover kills with the AR. i tried crouching and leaning behind crates but that did nothing. also any tips on how to overcharge to 200 health for the quick regen perk? this MP sucks at perk unlocking :( [spoiler]*Foghorn Leghorn voice* i say i say isay that last part was a joke, son.[/spoiler]
