I'm not a god tier player by any means, but I've seen a lot of people asking for pvp advice so I figure I'd give some advice, stuff that helped me come out on top of most fights.
- wear a headset, being able to hear is such a crucial part of Tarkov. I personally like M32's or Comtac2's
- Clear entire buildings before looting, I've died too many times by getting caught looting.
- Right hand peeks
- Reposition reposition reposition, keep the enemy guessing where you are.
- Heal, reload and re-pack mags when fights are at a stalemate, you want to be more ready than them when the fight continues
- Pop a painkiller pre-fight or as soon as you can. It will help if a limb is blacked.
- If you kill a solo, don't immediately loot, refer back to #5 while waiting to see if a teammate pulls up. Once you're prepped again is when you loot the kill.
