I remember back in the days you could go to the next map by going to the coordination 0:0 with wall hack enabled.
Recently I started playing this unprotected, old school server mostly for educational purposes (playing around with the data.pak, trying new things with CE, etc.) but the 0:0 map trick doesn't seem to be working.
Is there any other way to go to maps that require a minimum level, which isn't met?
