Reverge Labs has confirmed via Twitter that cross-platform play is going to be implemented so that PC and PS3 players can duke it out together. Here’s the tweet that excited both current and future Skullgirls owners.
@dnx3 We hope to have PS3/PC cross-platform play implemented a few months after the PC version is released… so definitely not GFWL.
The devs stated that the PC version will not be using Games for Windows Live, as the tweet mentions above, and they will have to be very careful about what, if any, DRM system is chosen.
Skullgirls will release on PC later this year.
