Activision's new Spider-Man title, Spider-Man: Edge of Time, allows players to play both the classic Amazing Spider-Man and Spider-Man 2099 in a twisted-up time tale the fate of the universe depends on. This behind-the-scenes trailer features the voice of Spider-Man 2099, Christopher Daniel Barnes. The game features what is called "cause-and-effect" gameplay. This feature allows players to see the consequences of their actions from one timeline to another. Sounds interesting. Spider-Man: Edge of Time comes out on October 4th.
