It worked for me...
Anyhow, This map suffers from some bad texturing (i.e. too much of the same stuff)
I got lost in the map a bit. I thought that there were only 4 pyramids, but in reality there are 6 (only four on the outside, and I realize that you specified that, but I didn't remember), I had to noclip out to figure that out
I had no idea what the buttons did, unless I noclipped to where the noises were coming from. I don't get the scene though. Are these actually supposed to be ruins of old pyramids?
Either way, I suppose this map was built okay-ish, but it suffers from detail and its immense size, it's HUGE and easy to get lost in...
