Here's the cover of the Ultimates book. Looks pretty fine, I think. Far as the story goes, here's a selection from the flap copy:
The alien shapeshifters called the Chitauri were defeated in a decisive battle, but suspicious activity leads the Ultimates to believe that not all of the aliens were destroyed in that cataclysmic attack. Stark Industries has developed a means of quickly and easily detecting Chitauri DNA, but the federal government refuses to adopt the technology, claiming that if the tech is widely available, the Chitauri will find a way to fool it.
Frustrated by the government's actions, Captain America takes matters into his own hands, leaking the technology so it can be manufactured and distributed throughout the country. His radical actions sow discord among the Ultimates and within the highest levels of government, raising a troubling question: Could this disunity and chaos be playing into the Chitauri's hands?
Look for it at the end of summer.
