Hello again, it's been a while.
While this page has been dormant for more than two years now, Enigma Protocol is not dead.
The mod has gone through many, many changes in the past two years. The original test chambers were reworked to play better than they did before, with all new chambers bringing the total count to 40 puzzles. All traces of custom textures were removed to fit in with the clean Aperture aesthetic. But the mod still remained in Aperture North, a separate wing of Aperture.
In April of 2017, the mod was stripped down and rebuilt from the ground up. No longer set in the fictional reality of Aperture North, Enigma Protocol now explores Aperture after the destruction of GLaDOS and the events of Portal. Puzzles have been rebuilt entirely, some being combined while others go completely unused.
If you would like to keep up to date with Enigma Protocol, I highly encourage you to join our Discord server, where I often post work in progress screenshots and videos, as well as interact with the community following this project. Feel free to also follow Hammering Out the Details, a development blog dedicated to the mod and its creation. The most up to date information will reach these two before anything else.
I want to thank everyone for their patience with this project, and I hope once it is completed that I will be worth the wait.
