If you donated at least $36 to the Skullgirls Indiegogo project, you'll be able to activate a beta copy of the game on Steam, compliments of your Humble Store account. Alternatively, you can still donate $36 or $81 to Lab Zero Games and nab an account that way. Updates are expected to flood this build, and just like every other beta, input for Lab Zero Games is appreciated.
The new DLC character Squigly is playable, so make sure you go ahead and test it out with the controller or fighting stick of your choice!
