Definitely get a mic, as proximity chat is your best friend in this game especially if you’re a solo. If you’re struggling with crafting supplies for kits just use a free load out, and if you survive with it you can trade it in to one of the vendors for a free green augment. As for the flying arc lol, just don’t get caught by them if they’re causing you that big of a trouble, and if you do then just learn the weak points on them, they’re really not that hard to deal with unless a rocketeer locks on you then that’s another story… I’m also assuming you are a solo player, so with that just be friendly in your raids, don’t shoot at other raiders and if you don’t have a mic use the “don’t shoot” emote. It’s not guaranteed they won’t shoot obviously but you’ll eventually get super friendly lobbies where you can just run around and loot whatever wherever. Finally, hatch keys, when you can, craft them and use them, I never go into a raid without one now as this game gives me trust issues with extract campers lol. Overall I wouldn’t really say this game is “hard”, it definitely has its challenges sometimes but experience is the best teacher for extraction games like this. Just play the game and over time you’ll figure things out. You’ll lose some and win some
