Add-on content and expansions can take a game you already love and give it longer legs. Just like core games themselves, DLC ranges from great to not-so-great. One thing that is consistent, however, is how difficult it can be to keep track of. The games themselves end up in "best of" lists or top selling charts, but DLC can come and go under the radar even for people actively trying to keep track of it. To remedy this problem, we've decided to round up all the significant DLC of the year in one place. We'll mostly steer away from smaller add-ons like costumes and booster packs in favor of new missions, stories, and maps. Some DLC in the list is for games that released in 2013, but if the DLC came out this year then it gets a spot. Read on for an alphabetical listing of all the important DLC of the year.

Assassin's Creed Freedom Cry
PS4, Xbox One, PS3, 360, PC

This content was originally released in 2013 as DLC for Assassin's Creed IV: Black Flag. In February, Ubisoft released a standalone version.

Official Description:
"Born a slave, Adéwalé found freedom as a pirate aboard Edward Kenway’s ship, the Jackdaw. 15 years later, Adéwalé has become a trained Assassin who finds himself shipwrecked in Saint-Domingue without weapons or crew. He now has to acquire a ship and gather his own crew to free the slaves and avenge them. Over three hours of new single-player gameplay."

Game Informer's take:
"If only for the opportunity to play as Adéwalé, Freedom Cry is worth checking out. On one hand, getting more of the same content is disappointing. On the other, that content is what made Black Flag fun in the first place, so getting more of it isn’t exactly damning." – Joe Juba

Batman: Arkham Origins 
PS3, 360, PC

Arkham Origins also released on Wii U, but the Cold, Cold Heart DLC was cancelled for that platform due to lack of demand.

Official Descriptions:

Initiation (Watch trailer)

Experience exotic locales including a bamboo forest and mountain-top monastery. This pack contains Bruce Wayne and Vigilante skins, four challenge maps, and a challenge campaign." 

Cold, Cold Heart (Watch trailer)

Along the way, he will uncover the tragic history of his new enemy, prompting our hero to attempt the impossible: save the victim and the villain.

BioShock Infinite
PS3, 360, PC

For those interested, an arena combat DLC also released called "Clash in the Clouds." The real meat for BioShock fans is in the two-part Burial at Sea episodes, which released several months apart.

Burial at Sea – Episode One 

Official Description:
Come back to Rapture in a story that brings Booker and Elizabeth to the underwater city on the eve of its fall from grace. Developed by Irrational Games, the studio behind the original BioShock and BioShock Infinite, this DLC features Rapture as you’ve never seen it before – a shining jewel at the bottom of the ocean, built almost entirely from scratch in the BioShock Infinite engine. The combat experience has been rebalanced and reworked with a greater emphasis on stealth and resource management to give the player a combat experience that merges the best parts of BioShock and BioShock Infinite. It includes a new weapon, an old favorite weapon from the original BioShock as well as the return of the weapon wheel, a new plasmid, new gear, and tears. Explore the city when it was at the height of its beauty, meet some old “friends,” and make some new ones, all through the eyes of Booker DeWitt. Why are Booker and Elizabeth in Rapture? What was the city like before everything fell to pieces? The answers to these questions and more will be found in BioShock Infinite: Burial at Sea – Episode 1. 

Game Informer's Take:
"On one hand, I’m thankful Irrational Games took this unconventional approach to DLC. Instead of re-using all of the same assets from Infinite, the team recreated Rapture and found a way to meld successful elements from several games in the series. On the other hand, the additions are minimal at best, leaving players to go through the same motions with a different backdrop." – Joe Juba

Burial at Sea – Episode Two

Official Description:
See the world through Elizabeth’s eyes in BioShock Infinite: Burial at Sea – Episode Two. Set immediately after the conclusion of Burial at Sea – Episode One, this final episode puts you in the role of Elizabeth as she journeys through Rapture in an effort to rescue the little sister she abandoned. Developed by Irrational Games, the studio behind the original BioShock and BioShock Infinite, this continuation of the Burial at Sea saga features parts of Rapture you’ve never seen before, includes modified stealth-oriented gameplay that brings you new weapons and plasmids, and involves nearly every major character from the original BioShock and BioShock Infinite. 

Game Informer's Take:
"This episode concludes the Burial at Sea story arc, which is one of the highlights of the whole experience. I don’t want to ruin anything, so I’ll just say that fans of the series will enjoy the returning characters and the way the worlds of Rapture and Columbia intertwine."— Joe Juba
