The Portal turrets have a Christmas song for you. Merry Science!

As previously noted in the Fallout 4 version , Carol of the Bells is the creepiest of all the Christmas songs. It feels like it was made for seasonal murder so it's perfect for a choir of Aperture Science's most musical turrets singing about neurotoxin. Something that's just so criminally underused at this time of the year.

Thanks to PC Gamer for that. I've included the lyrics underneath in case you want to sing along. "Neurotoxin! Is pumping in!" does have a lovely rhyming meter to it.

Time for some tests!
Shoot the subjects!

Make them all die! If they survive! Bake them a pie! The time is nigh! Testing is here! Let out a cheer!

Please sing along! This is our song! For the Animal King! We'll always sing!Guns we will bring! Bullets we will sling! Fill them with holes! That is our goal! Test if you dare! Are you still there? Please sing along! This is our song!

With joyful ring! We're caroling! Neurotoxin! Is pumping in! From everywhere! Filling the air! Filling the air! Filling the air!

Oh how they pound! Raising the sound! Throughout Aperture! GLaDOS is here!

Merry, merry, merry, merry science!
Merry, merry, merry, merry science!

Testing all year! With Christmas cheer! We'll only stop! When subjects drop!
