So, in case this post doesn't fall into oblivion: here is an early version of my first CSGO map...
I wanted to make a relatively small and conservative level inspired by train.
The only unorthodox concept is CT spawn, which is located around mid, so that it can be a more playable area.
This spawn placing allows for early fights if CT decide to push.
Furthermore, there is a vent from B to mid aka CT spawn.
