Zombie survival - Initial Feedback/First Impressions?

[Ace]

I was really enjoying the gamemode as a person with very minimal zombie survival knowledge/experience. I did feel that the hit reg was very off with most shots going through zombies at close range and headshots were basically impossible. Another gripe I have is that the progression as far as I can tell is too hard to get points for more weapons and the starting selection is very lackluster. I really like the idea of a skill tree to progress through and hope it is possible to expand on and add more interesting things into it. I hope it stays and fleshes out more to be unique like FRG is.
