Big mighty robot action! The men and women of Sentinel Squad are given their very first mission, and not all of them are going to get out of it in one piece! The secret origin of the Sentinels continues!
The news Sentinels are piloted by humans and the newest recruits have been put through the wringer. Their first mission was a catastrophe, as a routine assignment to guard a senator went terribly awry when a Hydra assassin revealed himself, along with a surprise secret weapon. After a long battle, the entire surrounding city was devasted, while the fledgling squad was unable to work as a team. One member, Alexander Lexington, a closeted mutant, was able to save the day, but not before raising suspicion about his powers, and not before another memer of the squad paid a permanent price.
