Desperado's was suggested before and it has a lot of glitches that allow you to get out the map. Highwon denied it on stream with me.
I remember playing Westwood a good bit when I started here. It was an okay map, but I felt like it was just too big and boring at the same time.
ive probably put 100h into the desperados map alone, its pretty air tight, the only "outside the map" is behind the main gate, which makes you trator food instantly. Other than that, you need as much prop surfing to go anywhere in that map as any other map
