I don't know about 75 test chambers, but Underground Story is definitely fun!

If you would like to see this mod broken to all hell hit me up on steam at INFERNOUX. (i'm a portal speedrunner, and the only chambers i did semi-correctly where the first couple before you get the portal gun)

Found a glitch. In the room with the descending ceiling that crushes you, the obvious solution is to Portal over to the other side of the gap. What I did was put a portal under my feet, and when the ceiling was all the way down, I tried going back through the portal. I basically teleported to the top side of the crushing thing.

This map pack sucks big time. In order to even play it, I had to move a bunch of files around because the person who made it didnt have the load file directing to the right folder. Then, when I finally was able to play it, the AI disabled itself. Also, a better name for this map pack would be "Portal: Copy and Paste" Because half the map's concepts have been stolen from other mappacks.

Challenging mappack with interesting puzzles, especially the second part is recommendable for every Portal fan though its ending came a bit suddenly. :/ All in all: 8/10 :)
