Few players were lucky enough to receive a free "The Frozen Wilds" expansion pack as a holiday gift from Sony.

Last week's rumors about Sony giving out free codes for the "Horizon Zero Dawn" expansion "The Frozen Wilds" have now been proven true. Comicbook reports that a few PS4 owners have indeed received codes for the massive "Horizon Zero Dawn" expansion.

"The Frozen Wilds" sends Aloy, the protagonist of "Horizon Zero Dawn" to the cold, far north called "The Cut." "The Cut" is densely populated by a tribe of robot-worshippers called "The Banuk." Aloy is tasked to help the tribe in getting rid of the "Daemon" that haunts the land.

Sony has also given out an exclusive "Holiday Theme" for the PS4 system, which features the classic PlayStation 1 logo at the background surrounded by festive pine trees and reindeer.

Additionally, Sony's PS4 "Holiday Flash Sale" is live again as of Friday, Dec. 22. According to Gamespot, the latest Flash Sale consists almost of exclusive games released for the PS4. This includes "Persona 5" which currently retails for $39.59 on the PlayStation Store. The "Yakuza Kiwami" remake "Yakuza" is also available and currently retails for $20. The latest "Star Wars: Battlefront II" is also on sale and retails for $35. The South Park game "South Park: The Fractured But Whole" retails for $30.

The "Assassin's Creed" series prequel "Assassin's Creed: Origins" is also included in Sony's Holiday Flash Sale, retailing for $40.19 for the standard edition. "Gran Turismo Sport" and "XCOM 2: War of the Chosen" retails for $39.59 and $30, respectively. But, perhaps the highlight of Sony's "Holiday Flash Sale" is the amazing bundle of "Call of Duty: WWII" and "Destiny 2." The triple-A game bundle currently retails for $77.99.
