Ok so I've been searching for a thread about putting level suggestions/ideas and I couldn't find one. If there is one please tell me and I'll move my thread there! I also know that there isn't a big chance of someone making this, but it is just an idea. So I think that a death road type map would be cool. Some well known ones are located in Bolivia. They are very narrow (barely wide enough for one car), have a wall on one side, and a vertical cliff on the other. Here are some pics so you know what I mean.
I would love to see a map like this, It looks easy to make just create a mountainous height map, smooth a place for the road (if you can even call that a road ) add foliage, detail, Skybox, and your done. Wouldn't need to make to many custom assets.
