Splinter Cell: Blacklist on Wii U lacks offline co-op play, despite having an online co-op mode.
Speaking with Nintendo Life, producer Liu Jun explained the offline mode's absence, "In order to ship at the same time as the other consoles, we unfortunately weren't able to delve into this feature.
"But we think Nintendo gamers will be really excited to get the game at the same time as other consoles."
While this might rile up some Wii U owners, the game does have a number of GamePad-specific functions not found in other versions. Check them out here.
