Earlier this week EA was charged with allegedly took tank designs from Warhammer 40,000 without Game Workshop's permission. This, however, is not true according to EA. They claim that the issues have been resolved and that the artwork in question was an “internal EA concept that was unintentionally released publicly”. The EA representative giving this statement also went on to say that:
“No Warhammer 40,000 tanks have ever made an appearance in Command and Conquer: Tiberium Alliances, and never will. Games Workshop and EA continue to have a strong relationship working together on Warhammer Online: Age of Reckoning and the new free to play game Warhammer Online: Wrath of Heroes which just entered open beta.”
At the top of the page is one of the images that started all of this. Reddit users Bro-jangles and corevirus posted other pictures talking about the similarities between two tanks that allegedly appear in EA's Command and Conquer: Tiberium Alliances as well as Warhammer 40,000.
