first of all go to editing mode ( become the little flying robot guy) by pressing up on the direction pad thing. then pause and go down to change game type pick the one you want bomb, skull, flag whatever onw you want. then go to the item spawning menu (i think you press x) then press rb and lb to switch item categories: scenery,weapons,etc. switch to goals for flag it should be called flag spawn point and flag return flag return is when the enemy sends their flag back to their base it goes to the flag return place. for oddball it should say skull or something like that for bomb it should be bomb spawn. You can switch what team the flag or bomb spawner belongs to by putting your cursor over it and pressing x there should be an option in the menu that pops up where u can select attackers defenders team1 etc. thats all i know about this subject pretty much hope i helped!
