Magneto is confronted on Genosha by agents of Shield and we get an interesting battle with Magneto's flashbacks to the Genoshan genocide. The most interesting aspect of this comic is we get to see how Magneto survived the Genoshan genocide as well as many of his thoughts on it. Its been one of the more important events in Magneto's history and we have seen quite little about his overall view on it and how it effects his thinking to this point until now.
We find out that effectively his people save him by getting him to bunker during the attack and he gives up on the concept of Genosha at the very end. I am just going to assume he was killing those mutants at the end because they were fatally wounded and he had no way to save them. Magneto in the end decides to hand himself over to the agents.
In all it was a really strong issue that does a lot to set things up for coming issues and Magneto's choice at the end should have interesting consequences. The art was picture perfect for the flashback scenes.
