Yesterday  Guilty Gear Xrd -Revelator- announced the release of Dizzy as a DLC for the game. Now you can download her if you're in North America, and she will be available for free until July 26th.

Incidentally, you can grab Dizzy even if you don't own the game yet, in case you plan to purchase it down the line .

On top of dizzy, a few more DLC have been released, but those aren't free. Below you can find the relevant links.

Downloading each DLC will entitle you to use it with both the PS4 and PS3 versions. You can see Dizzy in action here, and screenshots/art of the DLC here.
