It lists that content as part of the overall release, not specifically part of Early Access. It lists the early access and launch dates above the general content that is part of launch. The Allied Race isn’t unlocked until you can complete the over-all campaign.
I couldn’t tell you, Bushybuns, I don’t have a list of the entire campaign. That isn’t under Customer Support’s purview. I imagine the campaign stops at some point until the official launch date and will most likely be available after launch.
