A couple of ideas I have are
. Armour matching warpaints
. Possible battle-worn warpaints
. A possible warpaint using blood splatters
. a new scar or scars that have parts of the predators face exposed similar to Pam 4
That’s all I have but I’ll definitely have more soon lol
P.s sorry if I dragged on just got the game and have watched gameplay since it launched on PS4 originally (I only play on Xbox)
