Electronic Arts (EA) is apologizing today for a tweet sent out meant as an April Fools' Day joke from EA's Frostbite rendering engine – which powers games like Battlefield and Plants vs. Zombies: Garden Warfare – took a low jab at the struggling Wii U from Nintendo.

"Frostbite now runs on the #WiiU since it is the most powerful Gen4 platform, our renderer is now optimized for Mario and Zelda," read the tweet. Other tweets throughout the day included jokes that the engine would power the mythological Half-Life 3 as a Wii U exclusive. While Nintendo's struggling console is the brunt of many jokes these days with low sales and financial problems, EA boss Peter Moore came out today to offer the company's regrets about the tone.

Our apologies to partners @NintendoAmerica & fan @FrostbiteEngine’s poor attempt at April Fools not condoned by EA : unacceptable/ stupid."

While Moore says they are still partners with Nintendo and the Wii U, support for games from EA on the console has been nonexistent for the past year as the Frostbite engine is not designed to work with the system.
