Well, first, you build your camp. (You can go to 'Screenshots' to see some other amazing rouge camps.) Once you get at least one rouge in your rouge camp, a little menu will come up saying: "Hi! I found this den here and I was wondering if I could move in." Press backspace to chase them off your territory. Press enter to let them stay. ....Press spacebar to change you rouge symbol... Click 'Press Spacebar to change your rouge symbol' and it will choose a little symbol over your cat.
First, find a good place to settle with good hunting, water, and room to build. Then gather brambles to make thickets, and build walls. Set some moss or bramble down next to the thickets, and then add some prey next to it, and that attracts rogue cats. Also, you need to have your nest in the area where you want your rogue clan.
Don't forget you can put a shiny thing down to attract elligable mates! And don't bury moss or you won't be able to pick it up again. Also, you can end a rogue's name with kit or paw and their size will change. The same doesn't apply to you. If you need anything else, tell us!
