This is a map of Aperture Science! Here you can explore all of Aperture! When you spawn just look for the big Aperture logo near a small metal Building. I hope you guys enjoy it! 
 
This map requires the following mods: 
 
Malisis Doors 
Project Red 
Project Red Illumination 
open blocks 
portal gun 
BiblioCraft 
Immersive Engineering 
Ender IO 
AE2 
MineFactory Reloaded 
Extra Utilities 
Railcraft  
Computercraft 
Open Computers 
Chisel 2 
Carpenter's Blocks 
 
If you don't want to download all these mods then try to find a modpack that has all of them. I made the map in DNS tech pack so that has all the required mods. 

Note: This is a HUGE map so you need a beefy computer to run it at a good frame rate.
