The veteran action star told Ain't It Cool News that the sequel "delivers on every level" despite having its script toned down.
"The film is fantastic with Van Damme turning in an inspired performance... Our final battle is one for the ages. The PG-13 rumour is true, but before your readers pass judgement, trust me when I say this film is LARGE in every way and delivers on every level," he told the website.
"This movie touches on many emotions which we want to share with the broadest audience possible, BUT, fear not, this Barbeque of Grand scale Ass Bashing will not leave anyone hungry."
Expendables 2 was classified as PG-13 earlier this week at the request of Chuck Norris, who condemned the use of profanity in its screenplay and threatened to exit the project unless it was removed.
The Expendables 2 is released in theatres on August 17, 2012.
