what technique do you use in gunfights ?

Use a high rate of fire assault rifle like the advanced rifle with all the attachments and know when to roll and when not to. Try your best at baiting your opponent into rolling first, and then you can roll immediately after. If you have to roll first, do a glitched roll.

Roll straight backwards and as you're pulling the joystick back, do a sharp rock to the right. So centered, back, back rolled to right. It takes a bit of practice to get the timing, but it cancels the roll animation and you get back up a lot faster. Take note that motioning the stick back-left does not work.

Everything else is all about positioning yourself in cover and utilizing FPS mode to strafe. If you're at a disadvantage, do everything you can to even to playing field or even flip it on them. BP helmet/heist vest & bullshark are dirty and people will get mad at you but who cares it's in the game, I would have died in this clip had I not used this combo and it's why I have it as a saved outfit. They were 2v1 and had the high ground, plus my aim was slow as molasses and I still outgunned them.
