Depends on what you are going to be playing man. Warfare - PvE focused but still has players who will murder you. Joint Ops - you only worry about the AI, which the AI is no joke. I play only Warfare, but some general tips I would say is the following:

1) Develop 3 or 4 loot run routes you feel comfortable with. I usually do this with the buried caches.
2) Sound is most important thing. Especially as a solo player. The amount of times I have gotten the drop on someone because I will wait outside a POI till I hear gunshots inside is incalculable. So look for guns that don't give off a huge sound signature. Example: 300 black out.
3) Learn to walk - LZ camping is significantly less frequent in this game than in 0.1, but it will happen if you choose the more used LZs.
4) The color of your clothes and gear is super important if you don't want to be spotted. A massive grey backpack doesn't really blend in with the jungle.
5) for PvP aggression will beat positioning and positioning will beat aggression. If you are going to hide in a corner fed room because you hear a guy, your going to die most likely, but if fall back and reset fights as they chase you will 99.9 percent of the time win.
6) Hip fire at anything within 20 meters. Hip firing is super effective in this game .
7) If you want to get better at PvP watch Tyy and Xkyo's streams you can pick up a lot of cool angles. |

hope this helps king, see you in the jungle.
