Jane, who plays cheerleading coach Sue Sylvester in the musical-comedy, spilled the details about the programme's post Super Bowl return.
The 50-year-old told the Associated Press: 'It's got so much firepower.
'There is so much going on in the show that is crazy and funny and wild. I have a hissy fit the likes of which no one has seen before, where I try to destroy the locker room and principal's office. I try to shoot one of my cheerleaders from a cannon.'
The episode also sees the cast performing their own version of Michael Jackson's Thriller.
