The Kickstarter page is here. I think it covers things pretty well. If you're interested in superheroes in general, and computer/online games where you can play one in particular, this is worth considering.
This is the second of the three known successor projects to go to Kickstarter after last year's City of Titans successful run. Now normally I'm not big on pimping things online but I'm happy to spread the word on this one as I had a blast playing CoH and the team here seems really interested in creating a similar experience. Plus they appear to have made enough progress to get some gameplay video in their pitch.
Full Disclosure: I've backed it. I don't know or have any relation to the people working on the team but I am interested in this kind of thing so I am putting some money into it.
