Sentinel blueprints revealed

Bryan Singer seems to be loyal to using the Sentinels in the viral marketing for X-Men: Days of Future Past as we have yet another image of a Sentinel. This time it is a blueprint of a Sentinel helmet.

If you aren't aware of what a Sentinel is, they are basically big mutant killing robots created by Bolivar Trask (played by Peter Dinklage). We have already had a couple images of the machines in the form of a poster and a set photo of Singer next to one. There is no real word on exactly how much inclusion the Sentinels will have yet, but they are sure to be relevant.
