Talking about Sentinels, which I totally missed this weekend, there is a few good sources around to take some from that doesn't divulge from canon. Project Wideawake had Sebastian Shaw produce and supply the US government with Sentinels. Also Nimrod in game time is currently a latent sleeper virus waiting for the opportunity to find a new Sentinel construction program to rebuild itself whilst it's physical form is currently wandering as the young man who will one day become Bastion.<br/><br/>The ones that should appear go up to Mk.V that Shaw and the government are producing. A Mk VI appears around the time of Onslaught in the comics, also created by Shaw Industries, so it seems right now that Shaw should be the main supplier of Sentinels, though I love the thought of Nimrod being around in the background and coming up and forming as a new threat, like Ultron. :)<br/><br/>The Tri-Sentinel could also make a pretty massive threat, though it may be a bit much for this game. ^^;
