Well, I gotta say I am agreeing with Florin on this one. At the moment it is not really adding to the challenge rather than to the nuisance. I am all for the game to get harder but not at the cost of annoyance. These day should be over since the 90s. The Zombie attraction system is a nice addition but does not work properly. I just watched 6 of them running in circles while I was standing about 10 m away from them. A 7th one came sprinting at me across, I don't know, 100 m, completely determined to go for me. He saw/heard me, while I was standing through trees, the 6 other zombies and across 100 m. This is not challenging, it is annoying. Just in my opionion. Well, time to set up the Sandbox, since I fear that Survival won't be fun anymore.
