The Iron Man Mark V mod is among the many to use OpenIV

Since it was first published, the top review has been edited to add a link to a petition on Change.org, which calls for Rockstar to allow OpenIV to continue. It claims, “All modding used by OpenIV is for single-player use only to make the game more enjoyable, the software OpenIV was never used to mod multiplayer or Grand Theft Auto Online so it does not harm anyone.”

Rockstar disputes that. After word first surfaced that the OpenIV had received a cease-and-desist letter, the company released a statement saying it is only concerned with the tool’s impact on GTA Online.

“Take-Two’s actions were not specifically targeting single-player mods,” it said last week. “Unfortunately OpenIV enables recent malicious mods that allow harassment of players and interfere with the GTA Online experience for everybody. We are working to figure out how we can continue to support the creative community without negatively impacting our players.”

It’s unclear what effect, if any, the petition will have. It’s garnered just over 55,000 signatures as of this writing, with a stated goal of 75,000. It’s a sizable group of people, but also a fairly small number given GTA V has shipped more than 80 million units. Single-player mods, while popular, are a fairly small scene, and it seems likely that Take-Two will deem the integrity of GTA Online–which still represents a significant contributor to the company’s earnings–more important. We’ll report back as the situation develops.
