After all of the issues that have plagued Assassin's Creed Unity since it's launch, it seems as if Ubisoft have lifted up the white flag. In fact, the developers have now decided that not only are they going to give away free DLC to say sorry to those that purchased the game, but they are now planning to get rid of the season pass completely.
It has already been announced that the Dead Kings DLC for AC: Unity will be made free for everybody, but they've now confirmed that they will be ditching the season pass, which means it will no longer be for sale, and any future DLC will most likely be put on sale separately.
For those that have already purchased the season pass, Ubisoft have you covered - you will be able to pick out a game from their library and download it for absolutely free. There are only a few select games to choose from, but I think Ubisoft simply limited the choice to make it less confusing for their customers.
The games that will be free to season pass holders will be Far Cry 4, The Crew, Watch Dogs, Assassin's Creed: Black Flag, Just Dance 2015 and Rayman Legends.
Despite the season pass being removed from the game, Assassins' Creed Unity season pass holders will still get free access to all future content, so the free game is an added bonus. It's odd that Ubisoft have taken this route, but i'm sure this is the best way to keep as many players happy as possible.
