I get that the spiders are a "primary" enemy type - but unless you plan to give us back NPC Spawn Rate Control - Please decrease the amount that spawn while you are largely on foot (read: Between the crash site and the first forest where the wreckage is found) I got in a fight with no less than 3 packs of 3 - 5 spiders each just doing the tutorial (robinson protocol) upto getting into the personal lcoker on the EASIEST SETTINGS POSSIBLE. I ran into 0 other aggressive enemies for reference. Decide if you are making a horror game or a survival game please.
Until you have your first HV you go mining only with looking over your shoulders several times. It's creepy! But I like the thrill when you hear a certain Spider Sound and hurl around to see from where the buggers approach. Sometimes, I think its Seed-Related. I find a single BIG Spider within the Crash-Site... It seems to be OK after all. No change required, at least not for me.
Yes I have a fear of spiders in real life never mind in game. When they didn't spawn so much it was fine and I could play on my own but now I wont start a game unless my son is there with me in a coop. He takes care of the spiders until we get a little run around HV.
