PERK2 PREMI DUE VOLTE

Increases your rate of fire to 135%. Put more rounds down range quicker with increased rate of fire on any weapon you have, including your pistol. This perk is ideal for indoor fighting as you do not have to compensate for recoil as much, and can just spray doorways and rooms extremely fast. Warning, although you do fire faster, you waste more ammo and are less accurate if you fire too fast, so you will have to watch the recoil even more with this perk.

Let’s say your gun fires 5 bullets a second, it will now fire 2 more a second (well really 1.75 more a second, but it rounds up to 2, if you want hardcore numbers it's 135% of the normal firing speed). Your clip is emptied faster, but will definitely take down enemies in short order. The epic battle between double tap and stopping power. Here’s how I see it: If you like to get more metal out there and your guns fire rate is bad, go double tap. If you want to make shots count and your fire rate is already decent, go stopping power.
Double Tap is unlocked at Level 29, 1st Lieutenant 1
