Cheapest yet! The reason I bought a PS4!
The free DLC program for The Witcher 3: Wild Hunt consists of 16 entirely free DLCs that will be available for every gamer owning a copy of the game for Xbox One, PC, and PS4, and is applicable to all versions (digital and physical, standard and Collector's).
On Wednesday, 25 February 2015, CD Projekt Red will release the first bundle of DLCs (two of the planned 16)--the Temerian Armor Set (horse armour included) and a Beard and Hairstyle Set for Geralt, the game's protagonist. After this date, a DLC bundle consisting of two DLCs will be published every week, entirely for free. Gamers are entitled to the free DLC regardless of obtaining the game via pre-order or after launch. Instructions on how to obtain DLCs on specific platforms will be provided at a later date.
