Play an Original Avengers Story
Marvel’s Avengers begins at A-Day, where Captain America, Iron Man, the Hulk, Black Widow, and Thor are unveiling a new, hi-tech Avengers Headquarters in San Francisco. The celebration turns deadly when a mysterious enemy causes a catastrophic accident which results in massive devastation. Blamed for the tragedy, the Avengers disband. Five years later, with all Super Heroes outlawed and the world in peril, a sprawling adventure ignites when a determined young woman named Kamala Khan sets out to reassemble and rebuild the Avengers to stop the unchecked power of the secretive new force known as AIM.
