As Stanly mentioned in another comment, Born to Fire was playable the past few days as a partially open beta. However, I think it's finished if I'm reading the notice correctly. When I hit play its announcing that the "real" open beta is coming December 2. So I wasn't able to play it, but they do have a bit of a funny intro video up on the site. It seems to suggest there will be a medic class in this game.
