I have spent more time in the arcade editor than the main game. Having said that give my maps a try.
You can find my maps by typing my PsnID at the map browser or by searching the map names up themselves.
PsnID - Guitarist4Life44
Maps -

Steep(deathmatch)
Download and Enjoy!!!!!!
Feel free to add me on psn if you would like to share thoughts on the map editor, Play arcade mode, or try out each others creations.
~Happy gaming
