Mission: The Echo Frequency

An unlogged seismic anomaly tears through downtown Manhattan, unleashing waves of robotic scavengers from a rogue faction. The Avengers find themselves momentarily pinned down until a heavily armored, high-tech vehicle roars onto the scene. Armed only with custom-built vehicle gadgets and a heavily reinforced suit, you turn the tide of the battle. Impressed by your tech and tactical assistance, Earth's Mightiest Heroes want to know exactly who is behind the mask.
