Treyarch just released an update for Call of Duty: Black Ops II on Wii U. The Wii Remote control option obtained the Aim Assist feature, but players have unfortunately started to exploit it online.
A patch is now in development to fix these issues. As players wait for the new update, a Hotfix should temporarily address problems.
A message on the official Black Ops II forum reads:
Hello Wii U Community,
As you know, we recently added Aim Assist to the Wii Remote in a patch. While we are happy with our decision to offer this feature, the community has already identified a number of ways to exploit it. We have fixes to the issues ready, but unfortunately this will require a patch which is still being worked on
In the meantime, we are going to push out a Hotfix that removes Aim Assist on the Wii Remote as an option until we have it in better working order. Again, we do plan to bring it back, but it will have to be in the next patch.
We apologize for the issues found and for any inconvenience this change causes. Expect this Hotfix to go live sometime today.
