I think you can add and animation from flying birds from the trees when fire encounters happens. Off course for people know whe the shots come. Maybe the sound can attract the hungry wolves. Ass I said before this game it's so great to add wolves and anomalies that also can kill you to make it different from all battle royale experiences out there, so maybe make sense try to explore that area where you are the ones.
Don't really know if this is planned or something but all the thinks you plan in this interactive map way will be amazing. Cause no other company in the market do that and there's a huge amount of companies doing this kind of game.
Can die on a river is weather is bad, fire mechanics.... Don't really know maybe this is to difficult but I'm sure you have a list, from my point of view add as much as you can!
Thank you!
