I agree with kean, use defensive mode so players can’t lock onto you. Plus if a player does shot you, defensive mode gives you more health.
Also you can parlay. If a player kills you, parlay. This means the player can’t kill you for 10 mins. Which gives you a chance to get away.
Look into ability cards, those will help out a lot. Tonics too. You can find free tonics around the map.
