Hi everyone, I have a general question: which level do you recommend to get "Crushing"on Survival mode on solo? (to get one or three stars) When I was looking gaming sessions, it seems that levels 8-10 are quite a pain in the ass and a lot of people require help. So does it mean that levels 1-7 are doable solo in crushing and if so which level do I need to be? (and which are the better guns?) Thank for any help or advice.
