Twelve is the Key

Description
So, why twelve? Sometimes puzzles need one to think outside the box, wouldn't you agree? This time you have the chance to put that brain of yours into work and solve your way through huge, dark chambers, narrow corridors and sleeping turrets (or are they?!). Are you up for the task? You sure are!

Author's notes
Congratulations and thank you, fellow tester, for playing Twelve is the Key, my first map created in the Hammer editor. I hope you found the puzzles satisfying and that you enjoyed putting both of your hemispheres to use. Please tell me your thoughts, complaints, suggestions or your current mood, and I'll try to answer as soon as I can. Comments, aswell as criticism of the constructive kind, are well appreciated.

Version 1.2
The original Twelve is the Key was released on 20th of June 2014. As of 22nd of March 2016 Twelve is the Key has gotten a major update. You will find a complete list of the updates under the Change Notes. In short terms the map will now hopefully be a even more pleasent experience.

Thank you, especially for the Youtube playthrough. Would you mind telling me which areas you’d prefer a bit more lighting in?

Cool map. I would've preferred a bit more lighting especially in certain areas.

I used the cube as a shield too. One of my weaknesses is not seeing things right in front of me. Poor observation skills I guess. I managed to complete the map though.

I somehow completely missed the portable wall behind the first turret, and ended up completing the level by using the laser cube as a bullet shield ...

I feel like I need a tetanus shot after playing that level. Awesome and creepy, well done.
