"Test Chamber 74" - Portal map
When Portal game came out, it astonished me. It was the first logic game from first person perspective I played and there was no shooting .
After I finished playing the main story, I was interested in mapping for this game. At that time, there was a solid fan base on the internet who thought the same and some custom maps were already out there.
I have put all my ideas into this map and did my best to not make it too easy or too hard - so that people enjoy it. Therefore, having finished the original Portal game is highly recommended.
The map is quite big, contains new puzzles, textures and sounds. It gained some interest and positive feedback so enjoy it yourself!
