How can I create a top down world with 2d side scrolling combat?

i’m just starting out with unreal engine 4 so this will be a newbie question. i want an open world top down that has event or math.random enemy 2d side scrolling combat, but i have no idea how to do this. i’ve started mapping the top down world but i dont want to get too far into it to find out i can’t have the combat work. my google skills aren’t as good as i wanted, any help or tutorials would be greatly appreciated!

nothing? is this possible or should i just change what type of game i’d like to make?
