Electronic Arts is facing a class-action lawsuit over the promotion of video game Battlefield 3, with some disgruntled costuemrs claiming the company deliberately misled buyers in a promotional campaign for its version on PS3.

Legal firm Edelson McGuire has filed a complained on behalf of EA costumers who were promised a free copy of Battlefield 1943 when they purchased the PS3 version of the game.

EA later changed its promotion, announcing via Twitter pre-ordering customers would no longer receive Battlefield 1943, getting early access to DLC expansion packs, instead.

Battlefield 3 was released for Xbox 360, PS3 and PC in October. The game sold almost 2 million copies its first month in the U.S. alone.

Broken Promises

Those suing Electronic Arts claim the company's promotional shift, which greatly influenced pre-sale orders, was both premeditated and deceitful.

[Electronic Arts] misled and profited from thousands of their customers by making a promise that they could not, and never intended, to keep, Edelson McGuire's official filing read.

The law firm also takes the video game promoters to task for announcing the change over Twitter, an informal venue of which some of those who pre-ordered Battlefield 3 were not members. As a result, the suit argues, many gamers were enticed to keep buying the PS3 version of the game without releasing the promotional bonus has been changed.

This is not the first time EA, aligned with tech mega-corporation Sony, has been caught shortchanging its costumers. The company was recently called out for failing to deliver on an exclusive mode for video game Saints Row: The Third when it was pre-ordered for PS3. EA later offered Saints Row 2 as a free bonus to make up for the missing extras.

Customers involved in suing the company are not looking to score gobs of money from EA, according to Kotaku, though their lawyers are likely to get a big payoff if they succeed. All they want is their free copy of Battlefield 1943.

EA has yet to respond to the allegations.
