i would like to propose changes to how zombies detect players. 1. when a zombie hears a player action (be it a gunshot/footsteps etc.) they travel to the location of the sound to "investigate" (instead of agressing onto the player instantly when they haven't seen you). they could do this at any pace, i'd suggest that the louder the sound the faster they go to that location (i.e. footsteps slow, "quiet gun"; medium pace, sniper rifle; fast pace etc.) 2. zombies require a line of sight to the player to fully detect the players location and attack them, allowing players to attempt to evade zombies after they have been heard by them by hiding/moving to another area without being heard again. 3. if a zombie loses its line of sight with a player for too long it returns to chasing the sounds the player makes rather than the player itself. i believe these additions to zombie behaviour would allow for more complex and satisfying player/zombie interaction (at least for me lol). my apologies if something like this has already been suggested.
