It is about the aspect of the game, indeed I think it can be very interesting to put a deeply horrifying aspect by immersing the players in psychological horror. This would strengthen the creepy side of the Predator universe which frankly deserves to be respected. I also suggest putting a map at night, with rain, and thunder.
Try to find a balance between the predator and the survivors. To begin with, solve the problem of the Gatling and the sniper, which clearly runs up against the predator and clearly does it wrong.
And for the rain etcā¦)
