AppAdvice: The game starts out with a transmission from none other than Nick Fury himself. He will brief you about The Pulse, which has busted open the top secret Vault of the S.H.I.E.L.D. facility located in the Rocky Mountains. This means that a bunch of imprisoned super-criminals have escaped, and the Avengers need to be assembled to figure out who broke open the Vault. Meanwhile, Fury orders the Hulk to go on ground to round up all of the baddies that have escaped.
