Marvel: Avengers Alliance takes place in the wake of a galaxy-wide disaster, known as the Pulse, which exposes Manhattan to attacks by Marvel's most deadly Super Villains. Players are recruited as an agent of S.H.I.E.L.D., the secret espionage and peace-keeping organization of the Marvel Universe, to assemble and lead teams of Super Heroes with a mission to keep New York City safe from the clutches of such enemies as Loki, Doctor Doom and Magneto, as well as sinister criminal organizations like Hydra and AIM. less
