A Christmas special game created for Christmas 2023 and released on the 23rd. It features Christmas decorations and a restaurant named "definitely NOT an Advertcorp owned restaurant". The building's exterior is marked with graffiti. Its a chaotic time with various Epix Gamer Group members under the "ADVERTcorp worker" rank roaming around and many elves. Two ADVERTcorp workers greet the player in the front of the restaurant.

In the restaurant's kitchen, Spongebob and Sonic-humanoid chef roam around. The kitchen displays posters instructing kitchen staff on how to use the appliances. There are ovens, freezers, coils that spawn in objects, a dangerous, patented "Insta-Cook" machine and a microwave which plays a role in acquiring a badge.

Above the restaurant, a few ADVERTcorp workers are having a banquet. 

The player is immediately granted a Gravity Gun, as seen in the ADVERTcorp game, and a white glove that allows the player to slap characters and other players around. The Gravity Gun functions the same as it did previously, allowing the player to pick-up and blast objects.

​

A few billboards throughout the map suggest ADVERTcorp is losing money and that their marketing budgets are declining hence the messy posters. This could be due to a number of reasons such as their workplace conditions, their employees rebelling against their management and employees taking days off over Christmas. 

A couple signs in the kitchen briefly describe how appliances work, such as the "Insta-Cook" machine and the machines that materialise food out of thin air with a press of a button. One billboard describes the "Bomb Ball 9000" which seems to be a more dangerous version of one of the balls from the ADVERTcorp game. The bomb ball will explode on touch with anything making it very dangerous. it can be utilised to the player's advantage by picking it up with the Gravity Gun and attacking things.
