Okay, so this is a bit old, but I had never read these despite the fact I love the Ultimate Universe and all of the titles (except Ultimate Fantastic Four). In this volume the Ultimates and the X-Men go to Russia to find the source of a communication sent to the whole planet. What they find is Russia's answer to America's program during World War II which created Captain America. Both supergroups find creature after creature that have been lying in wait since the '40s. This is a killer beginning to Ultimate Galactus so I will be reading through the rest of these.
