How the Saints Save Christmas is the second mission pack for Saints Row IV. It has 3 missions and will be priced at $6.99 (around £5.00) but will be free to those who had purchased the Season Pass for Saints Row IV. It got an early release on the 10th December, one day prior to its supposed release.
Shaundi also calls The Protagonist 'a Grinch' although the character doesn't know what it means.
The snowman with a machine gun is wearing a shirt that says "Now I have a machine gun Ho-Ho-Ho." This is a referrence to the movie Die Hard. Also the snowman's design is the same as the narrator of the "Rudolph the Red Nosed Reindeer" Special.
Judging by the collectable text adventure, the DLC takes place after the main game.
An objective in "Miracle on 3rd Street" to lick an electrical pole is a reference to the film A Christmas Story, in which the main character (Ralphie)'s friend, Flick, is dared, then 'double dog dared' to lick a frozen flag pole, and gets his tongue stuck to it.
