The Beyonder tells Spider-Man he is to lead a group of Spider-Men from different dimensions to stop Spider-Carnage from opening up an inter-dimensional hole and causing an explosion that will destroy all realities and dimensions.

The game revolves around an artifact known as the Tablet of Order and Chaos.
