using his own fingernails, but still cool). The issue ends with Hawkeye setting out to track down the Serum.
The setup points to a superhuman arms race, with Hawkeye looking for the Serum and battling large numbers of enemy superhumans. Hopefully, future issues will focus more on Hawkeye himself, and make his character integral to the story, since right now, there's no reason for him to be the lead character.
The issue is written by Jonathan Hickman, who's also writing the redundantly titled Ultimate Comics Ultimates. My biggest problems was the heavy exposition, especially when the SEAR scientists were discussing their evil plan. A picture is worth a thousand words, and there were several scenes where characters said things that were perfectly clear without explanation.
Anyway, this was a pretty fun issue, and I look forward to seeing where the series goes.
