EA has officially apologized for what it has judged to be a couple of mean-spirited April Fools' jokes at Nintendo's expense, tweeted out by its proprietary video game engine Frostbite.

2014 April Fools' Day Gaming Pranks

The tweets, which have since been deleted, came from Frostbite's official account and ridiculed the Wii U for being underpowered.

"Good news, we have finally fixed and optimized our 'netcode'. Uses quantum entanglement for Zero Latency connections. Exclusively on #WiiU."

"Frostbite will power #HalfLife 3, coming out summer 2014! #WiiU exclusive."

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



— Peter Moore (@petermooreEA) April 1, 2014

"Frostbite now runs on the #WiiU since it is the most powerful Gen4 platform, our renderer is now optomized for Mario and Zelda."It appears EA didn't see the funny side. Not only were the tweets taken down, but EA's Chief Operating Officer Peter Moore apologized from his personal Twitter account, calling them "unacceptable" and "stupid."EA revealed last year that it currently had "no games in development" for the Wii U, in part because Frostbite Engine 3 will not support the system. Earlier this year, Moore clarified that Nintendo "never have been, and never will be, 'dead' to EA."
