From GameWatcher: “Total War: Rise of Mordor has been removed from Mod DB following a DMCA takedown claim filed by Warner Bros.. Development of Total War: Attila’s ambitious total conversion mod will continue, according to the developer, who is also looking into rebranding to avoid similar issues in the future.
“… we have received word from ModDB officials that Warner Bros has sent them a DMCA takedown request to remove Rise of Mordor from their databases. We are grateful to ModDB for giving us time to put our affairs in order before the page is taken down,” read a post announcing Total War: Rise of Mordor’s departure from Mod DB.”
