Marvel superheroes coming to Disney Infinity in September

If you've been thinking Disney's hit Infinity game isn't quite "super" enough, we've got good news for you. Marvel's Super Heroes are finally on their way.

The Guardians of the Galaxy are joining the previously announced additions of the Avengers and Spider-Man. They all will arrive with Disney Infinity 2.0: Marvel Super Heroes on Sept. 23.

You can pre-order the new arrivals now. If you pre-order the starter pack, Disney says you'll get a free Marvel figure of your choice with the pack.

Disney Infinity already is a massive hit, with more than 3 million starter packs sold. That adds up to more than $500 million in revenue in just the past year.
