Test Chamber 74 is a mod for Portal, created by Meki.
Description:
First Portal map by Mek, large and of intermediate difficulty. Having completed the original game along with the advanced versions of puzzles is a big advantage.
Instructions:
Open the .bmz file in the game under the Bonus maps menu and then under the button Import bonus maps... You won't probably need the "scenes" folder, because the only one custom scene rarely works. From what I know, it will work for those players, who have Portal set for not using the GCF files, but the extracted files in Portal directory instead. If this is your case, then just move the "scenes" folder into your "portal" subdirectory of your main Portal directory. It should ask whether to overwrite the "scenes.image" file. Backup the original one (just in case) and overwrite it with mine.
