|Tweak, upon completion of Fast||200 RP, $1440, The Furious - Enhanced|
Immediately following the completion of Fast, you’ll be given the follow up from Tweak. This time he wants to create a performance enhancer to increase your melee attacks. Once again you’ll need to gather the necessary ingredients unless you already possess them. Mustard Plants can be found all over but the closest is in the hills to the west of your location. Once you have the ingredients in hand, head over to Tweak.
Punch the Angels into the fire pits 
Back outside, pick up a dose of The Furious and inject yourself with it. This significantly increases the impact of your melee attacks and you’ll need to melee six Angels into any of the three fire pits around the area. Try to create a little distance so that when you strike them, they’ll fly back into the pit. Too close and they’ll sail right over the pit. Defeat any remaining Angels once you’ve achieved the six needed and return to Tweak to conclude the mission.
