It’s been ten years since the release of critically acclaimed real-time strategy game World in Conflict, so from December 4 (9AM PST) through on December 11 (2AM PST), you’ll be able to download World in Conflict and its expansion (Soviet Assault) for free.

Then, in honor of the tenth anniversary of the first Assassin’s Creed game, you’ll be able to get Assassin’s Creed IV Black Flag for free from December 12 (6AM PST) through December 18 (2AM PST). As long as you download the games through Uplay during their free periods, they will be yours to keep and play whenever you like.

Developed by Ubisoft Massive, World in Conflict is an RTS set in an alternative history in which the Soviet Union invades the United States in the late 1980s. You play the role of an American commander tasked with marshaling air and ground units in skirmishes ranging across the U.S. (and into the U.S.S.R. in the Soviet Assault expansion). Learn the strengths and weaknesses of your armies, then leverage them as you wage war on destructible battlefields in the solo campaign or in online multiplayer.

In Assassin’s Creed IV Black Flag, you are Edward Kenway, a pirate out to make a name for himself on the tumultuous Caribbean seas by sailing your ship among the isles in search of plunder, attacking enemy vessels, and diving below the waves for lost treasures. Become embroiled in the conflicts of the era and discover your connection to the series’ age-old struggle between the Assassins and the Templars.

Set yourself up for a holiday filled with fun and free games by downloading World in Conflict and Assassin’s Creed IV for free this December.
