Ok, I decided it would be better to make the map square instead of rectangle, not that big of a difference considering the scale of this map. Note: This isn't complete, I couldnt get the nobuild shader to work (sorry, I'm novice when it comes to shader code, I hope to fix it soon). I have several things to say about this map that you should know before you play it.
#1. Brushes with red stripes are teleports, I decided that teleporting to each level would be more effective, but since you are only testing you will probably use devmap. In which case you would want to use /noclip.
#2. Brushes with blue stripes are buttons (used on floor 2, 4)
#3. The platform moving from on platform to another takes twelve minutes to get to point B, but is quite visible.
#4. Because of the size you will find the map quite desert, I suggest changing the speed to 1000 or it gets too hard to navigate.
First floor: Human reactor, human spawn, human armory, alien spawn, teleport to floor 2.
Second floor: Button elevator, teleport to floor 3.
Third floor: Auto elevator, teleport to floor 4.
Fourth floor: Button and auto door (Button door is to the right when you teleport in, auto too the left[teleport is passed the button]) teleport to floor 5.
Fifth floor: Func_train (platform moving from point A to point B), teleport to floor 6.
Sixth floor: Shader currently broken, will fix soon.
