The Winter Testing Initiative

A new testing course has arrived just in time for the holiday season! Can you make it through the five festive tests GLaDOS has in store for you?

~We strongly recommended playing this map in high shader detail, as certain custom textures will not look as good with lower settings.

~There is an extra special secret hidden in the map....read the signs carefully to find it!

~Difficulty: Hard
~Estimated Time: 40 minutes - 2 hours

Q: I can't solve (insert puzzle number here)!
A: A video walkthrough is available on this page.
Q: How long did the map take to make?
A: Seven months.
Q: How did you get the test chamber/map to look like this?
A: Hammer World Editor (also known as Portal 2 Authoring Tools Beta). Keep in mind most the holiday models and textures are custom made and unavalaible to the public however!
Q: Will the team be doing any other holiday maps?
A: None are planned at this time.
Q: Can you give me <insert custom texture or model here>?
A: To keep these custom elements special, and to respect all the effort the creators put into them, they will not be released for public use.

I rarely comment on maps, but holy cow that last part took some thinking. Thanks!

Such a fun map. I love maps that make you think and don't require special skill based moves.

I'm familiar with your puzzles. This was one of your best!

@Saya Just for clarity, Mevious helped playtest these puzzles, but was not the creator of any. Happy to hear you enjoyed the map!

I thought I smelled Mevious on this map. Funny then to see him in the credits. :) Mevious maps are uniquely elegant. This was almost like 3 of his packed into one. A++ :steamthumbsup::steamthumbsup:

Fun Christmas map, cool texture and fun levels, but it was a bit short (took me 30 mins).

how do you get to the secret? does it have anything to do with the tube in the final chamber?

the last chamber really sucks, loads of the test is hidden for the majority of it and there's a real spike in difficulty overall leaving a really sour taste when i finally finished it :/ :steamfacepalm::steamfacepalm::steamfacepalm:
