Poor Wii U. No matter how much it tries to compete with the real consoles, it just can't. Not when add-on content for the Wii U version of games arrives months after that of the PS3 and Xbox 360.
According to the official Injustice: Gods Among Us Twitter, add-on content for the Wii U version of NetherRealm's fighter will be available this summer. So if you are a Wii U owner hoping to play as Lobo or the soon-to-be-released Batgirl, tough noogies, you gotta wait.
This is just another blow in the long line of disappointments Wii U owners have had to endure. We're STILL waiting to hear if Activision has plans to release Call of Duty: Black Ops 2 DLC on the Wii U. Seriously, this is getting pretty old.
