Command & Conquer™ Franchise Modding Guidelines

EA appreciates the passion that our players and community members have for our games. In particular, we celebrate the Command & Conquer community Mods that have helped fans engage in our C&C games for decades. Members of the C&C community have asked us what community Mods they can create and distribute. This Policy applies to all modifications, alterations, or extensions of the C&C video games and universe, including add-ons, modified UI and new levels, maps and updates. EA does not object to your use of the C&C video games in your community Mods, provided you comply with the following guidelines.

Not for commercial profit: Community Mods are just that, Mods focused on coming together over a shared passion, not a money-making venture. Your Mods must be non-commercial and distributed free-of-charge. Therefore, Mods cannot be sold, licensed, rented for a fee, nor can the Mod contain features that would support monetary transactions of any type. Mods may not be used to advertise any goods or services.

In addition, your Mods must not be used to solicit donations, except as follows: EA recognizes that the time and resources needed to create Mods can sometimes be substantial. Accordingly, Mod developers are allowed to fund their development costs through donations, subject to the following restrictions:

Requests for donations must be limited to the Mod website or distribution site and not appear within the Mod gameplay itself.
Donors may not be provided with any in-game special advantages, such as private access to a Mod, special levels, graphical markers, special text, abilities, units, maps, etc. That is, all users must be able to play the same Mods without having to pay extra to do so.
Donors that are corporations, limited liability companies, partnerships, etc., cannot be listed in the credits section of a Mod; only individuals may be listed.

Respect the rights of others: Your Mods must not infringe any copyright, trademark, patent, trade secret or other intellectual property right of any third party and will not include content that is unlawful, tortious, defamatory, obscene, invasive of the privacy of another person, threatening, harassing, abusive, hateful, racist or otherwise objectionable or inappropriate. EA requires that Mods not include any material that would not be allowed under the age ratings for any applicable C&C game(s).

No EA affiliation: You must include the following statement prominently at the top of your website and in at least one root-level license file in any source-code repositories for your project (e.g., a README file or equivalent): “EA has not endorsed and does not support this product.” Do not promote your Mod in a way that suggests that it’s endorsed or approved by or affiliated with EA in any manner or that it is an official product or service of EA. Do not use EA artwork, logos or trademarks (including game logo treatments, the names Electronic Arts, EA or “Command & Conquer” or the logos or names) to promote your Mod. However, you may use plain text to state that your Mod is for Command & Conquer and/or for a specific C&C game or expansion pack in the franchise (e.g., “Command & Conquer,” “Tiberian Dawn,” “Red Alert,” “Renegade,” “Generals,” and/or “Kane’s Wrath,” as applicable).

Safety & integrity: Your Mods must not jeopardize the integrity of the gameplay or harm the experience of others and must not interfere with or disrupt any of EA’s services, servers or networks, such as by introducing malware or by circumventing any of EA’s content protection measures for its services. To maintain the integrity of C&C and ensure the best possible gaming experience for our players, EA reserves the right, in its sole discretion, to revoke permission to use, distribute or make Mods at any time, to disable any Mod, and to take disciplinary action against players who take part in any of these activities.

Intellectual property ownership; license from EA, C&C assets, including game code, art, music, and all other content, are and shall remain the sole and exclusive property of EA (the “C&C Assets”). To the extent any C&C Assets are used in Mods, EA grants the Mod creator a revocable, limited, non-exclusive, non-commercial license to use the C&C Assets solely in connection with, and as a part of, the Mod and subject to the terms of this Policy. Your Mod must not include any music files from any C&C games. EA reserves the right, in its sole discretion, to revoke this license at any time.

Abide by all other EA rules: These guidelines supplement and don’t supersede any other EA rules that apply to your Mod, including the GPL license terms and conditions under which we have distributed both our C&C Remastered Collection DLL source code and source code of some of our other C&C games, and the EA User Agreement, which are specifically incorporated into this Policy. In the event that the terms of this Policy are in conflict with the terms of these other EA rules, the terms of this Policy will supersede and govern. For clarity, Mods constitute “UGC” as that term is defined in our EA User Agreement.

Please remember that EA does not pre-screen, endorse, or specifically support any C&C Mod. Please use Mods with caution and understand there may be a risk.

Thank you for your interest and we hope you continue to enjoy our games.
