Sorry if this has been posted before, I'm new here, and I don't see a search function.

Sylvester Stallone has co-written a comic book called "Expendables Go To Hell". I've seen some people online say that the plot to the comic is what was intended for Expendables 4, but it would have been too expensive to produce as a movie. However, I've also seen other reports online that this comic is completely different to the proposed plot for the 4th movie.

Either way, for Expendables fans eager for a sequel in any form, check out the book on Indiegogo. (As a new member, I see I cannot post links).
