Been loving this game so far, but easily got the 10 milestones on the first mode the game lets you play (the one tagged as accessible). I wanted to try jump into the deep end and as the title says, I tried the ancient warriors map on hardcore. I find that I'm ok until roughly the 2nd hour of play time , where a sudden surge in heavily armed raiders attack in overwhelming numbers and absolutely demolish me. Do I need to rush population to overwhelm them? Do I need to rush better weapons?

(I'm am building a wall around the settlement, watch towers and stands asap, then focusing on mining and knowledge points currently. I instally tried alot of wheat farming and animal farming to take away the need of hunting as much, but this fucked up my workload)
