This is my first SM map ever, I made it with my cousin over the course of a couple days. It's a multiroute Heroes map, with a lot of maze-like tunnels and a few big caverns, with only the spawns and the pole's area on the surface. It's pretty hard to defend because of the lots of routes, so we made some tunnels that can only be accessed from the defenders' spawn, that should balance it out a bit. It has an intro as well.
If you add it to your server, please let me know here, I'd love to check it out online!
Good luck, have fun!
