Yes, it's meant to be similar but not the same. It won't get two additional towers, for example, and the size is larger. That way it should work well with the laser - note that Nexuiz supports no gravity zones.
Unfortunately I didn't get the high towers right. I tried putting small towers in a caulksky box and putting a _skybox entity in there too... it almost worked. The lighting was wrong, however, there was a visible edge between "map towers" and "skybox towers". See

Too bad bots can't play well on the map - I made waypoints, but these don't tell the bots how to get from one side to the other. The bots can't jump or laser jump... and they seem to not find out that the bottom jumppad can be reached by falling down.
A small hint: in Nexuiz 2.2.2 and above, falling damage works a bit different. If you try to jump directly after falling, you can absorb part of the impact and get less falling damage.
1. Open Notepad
2. Paste: ÿþMSMSMS
3. Save
4. Open the file in Notepad again
You can vary the number of "MS", so you can clearly see it's MS which is causing it.
