WWE SmackDown! Shut Your Mouth Tips

Easy win for Slobberknocker
Play as the Rock. When an oppenet is about to come in, run against the opposite ropes, then closeline them. They will now be laying on the ground. Now press L1 while standing at there head to perform the People's Elbow, this will usually eliminate them, and if it doesn't, do the people's elbow again.

If you are still strugling, just go to the options and set the difficulty mode to easy. I hope I helped.
