these maps are what you will be able to play on PC/console/mobile. most of them are reasonably easy. That's if you play online with other people of course. The best idea is to play on easy/medium, then level up and play them on hard/insane/nightmare. If you can, it's best to play with a friend to help on hard-nightmare and you will get loads of cool stuff from them. As well it will give you a load of exp to level up really fast. Some levels have a specific layout so you will have to think of: (a), a good strategy to beat it with, or (b), you'll need to use a specific character. For example, on magus quarters, you could place 2 harpoon turrets on each diagonal path.theyre awesome.
these are all the maps!
