Some guns are very good and others are guns you could just do without. My personal favourite is the double pump. It's really easy to use and it's good in close combat because if you run out of bullets in the first gun, just switch to the next. If you find a sniper take it. Because if you can make a good base in the circle and it's safe then camp up there and snipe. Also in your house, put two floors and then on the roof of the first put some traps that'll come down and kill them when they go to your base. Once someone has used them traps you'll need to be careful because they can come up and shoot you so keep checking behind you all the time. Also i recommend the scar. It's very good in close and long combat. Especially legendary scar.
