After undergoing setback after setback in adding additional content to their game, the Skullgirls team made the decision to hold an Indygogo fundraiser to get the wheels moving again.
The first DLC character, Squigly, will be free for a limited time after Lab Zero meets their goal of 160,000$. In addition Lab Zero is offering numerous other awards that you can claim dependent on how much you donate to the project. There are customs palletes, soundtracks, Tf2 hats, and a beta copy of the pc release. If Lab Zero makes 200,000 more dollars they will put in an additional character, Big Band. If enough money to fund a further character is collected then that third character will be decided via a community vote.
You can donate here.
