Marvel and Disney are following up their hit "Avengers Alliance" social game with "Marvel: Avengers Alliance 2," the companies announced today.

The sequel, described as a 3D visually-enhanced mobile game, finds Marvel's heroes traveling across the globe as they investigate the disappearance of entire cites. Adding to the mystery is the deposits of Iso-8 left behind after each city vanishes, and the villains who seize upon the confusion, taking the opportunity to create more chaos. Players level-up, earn the ability to customization their heroes and more.

The full roster and plot details have not yet been released, but the clues provided in the launch trailer -- the planet under seige, Death looming over Earth saying, "Show me what you would do for love," followed by a deep-voiced answer: "Everything." -- indicate Thanos is likely the story's main villain.

"Marvel: Avengers Alliance 2" will launch in beta in early 2016.
