michael talks a bit about what they're filming in chicago

of course when it comes to michael bay he likes to keep his films secret, and not give away everything. but he was kind enough to at least tell us whats going on in chicago. he says "is at the very end of the movie and the city is under alien attack, so it's very critical and important to the film's climax." he also mentioned this: "a number of base jumpers who are part of Josh Duhamel's unit. The heroes in this movie have very few people coming to help them this time. I like to think of it as the 'Black Hawk Down' version of 'Transformers' it's much more intimate in terms of what's happening.Something very bad has happened to America and this is at the very end of the movie."
