... My 3rd release. (Released January 2000)
I noticed early on that the most played maps were the default valve releases, problem was, each map had only portions I felt were good, so in my arrogance, I chose portions of some and adding my own works created a rather well laid out map.
My ego swelled because I received dozens of emails chastising me for decompiling the originals and using them in my own map.. All along these people never realized the compliment they were bestowing upon me. The maps are 100% my own creation, all made from memory.
Though the map is way too huge and has a somewhat muddled/boring theme, you have some very nice sturctures in there, like: the black hallways that themselves extend into the room--never saw that before!--, and the room with the exposed trusses was quite interesting too. There were other interesting areas, but my memory isn't that good!
Nice Work!
