Nano and I had the same idea hahaha. But his map is a remake and this one is an inspiration.
The map is pretty small, because while I was doing it I had in mind that it was mainly for 1v1. There is no weapons because I figured it out for octagon type mode or training your aim.
Anyways the maps can support 3v3 but it will be very excessive. So you can play a 1v1 or ffa with 4 players.
Another thing is that I knew about this map before generalkidd uploaded his video, I thought it was a custom map because the video that I found was called "Earth City".
