New details have been revealed for Saints Row 4 expansion 'How the Saints Save Christmas.' The classic holiday story, which in a rare change of pace for the Saints series is based entirely on fact, will introduce new Achievements and side mission types spread across the digital world of Steelport.

The Achievements are as follows:

•  A Saint Gets a Gun: Ring all the bells in town in 'Miracle on 3rd Street' - 5G
• How Many Licks Does it Take?: Lick the candy can barricade all the way through in 'The Fight Before Christmas' - 15G
• Get That Kid to a Psychologist: Find all the snowmen vignettes in the North Pole - 5G
• Dear Santa: Find all the letters to Santa in the holiday missions - 5G
• A Very Genki Holiday: Complete all instances of Genki Holiday - 10G
• Make a List, Check it Twice: Complete all instances of Naughty and Nice - 10G

Additionally, there are four Secret Achievements that are likely earned by completing story missions.

It seems like Letters to Santa will replace the audio diaries that were scattered throughout the normal game, while Genki is set to return yet again with what is most likely just a re-skinned version of his usual mascot brawl.
