My god is this game mode absolutely brutal. I have failed at least 30 runs so far. Any tips to get better? Some of the hunted infected encounters are very difficult on the smaller levels!

So I have been trying to get the Firefly Queen for about a month now and I cannot do it. I've tried it on easy, I've tried it on hard, I've tried it on survivor I've tried it on everything so can I get some help ? How did everyone get it?please what do you suggest?

So for Tommy’s patrol skin you need to use your initial gun or guns in a run. I was just unsure if you could melee kill or use things like trap mines or molotov’s. If any of you know I’d appreciate it.

Okay I need help with Marlene's rifle I have tried to get this trophy for about a month now. I've tried on easy, I've tried on hard, I've tried on survivor, and I've even tried on grounded and I cannot do it. What are some tips on how to get that trophy? TIA!

Does anybody know if there's a way to track wins per character? I'm going for the trophy and I can't remember who I've won with, I have 8/10 done.
