I have four suggestions to share right now, and one of them is the addition of a kill log, which would be fantastic.
Another idea is to have a map and GPS receiver that accurately shows our location in-game, as these items can be quite difficult to find most of the time.
Additionally, it would be great to have the option to type in-game, with a global chat toggle and the ability to send messages to players within a certain distance instead of just globally.
Lastly, I think it's essential to introduce bandit and friendly skins. After accumulating a certain number of kills, players should receive a bandit skin, while those who refrain from killing on sight could have their own unique skin aka friendly skin which is obtained by helping other players- feeding, giving medicine, etc.
