Dozens of brave heroes spring to action at that clarion call. Superhumans from every walk of life rise to defend Earth from threats so great, no other force could counter them. Which ones will answer when you send out the call?
Decide quickly - the fate of the world hangs in the balance. Menaces such as Kang the Conqueror, Baron Zemo, and Loki await inside. You are all that stands between them and a conquered Earth.
