You may remember Tribute from their last game, Wizorb. This time they've reunited with more of the Scott Pilgrim vs The World: The Game team
If you pledge $15 you're guaranteed a copy, and you get Wizorb for free.
They're looking to raise $75,000 as their goal, but if they hit $175,000 they'll add 4 player online co-op as well. There's a full breakdown on the kickstarter page of all the tiered unlock things.
