A law firm in the United States is attempting to build a case against Electronic Arts regarding the development and sales of Battlefield 4.

Holzer Holzer & Fistel is investigating whether EA complied with the federal securities laws when making statements about the game between July 24 and December 4.

“Specifically, the investigation focuses on statements issued during that time regarding the development and sales of the Company’s Battlefield 4 video game and the game’s impact on EA’s revenue and projects moving forward,” reads a press release.

The multiplayer in the game’s PC and next-gen versions has been plagued by bugs and connection issues, with many players reporting being dropped, booted, or simply unable to get into a game.

On top of that, the introduction of the game’s China Rising expansion appears to have created a number of new problems.

As a result, developer EA DICE has halted development on all Battlefield 4 expansions until the core game is up to scratch.

It has also suspended work on Battlefront 3.
